wiring problems

[Plymouthy Adams]

your standard little square Bosch style relay that is so common today in 30 and 40 amp variety is easily wired...the post are numbered with the energizing coil on pins 85 and 86 the battery supply to your device is input on pin 30 and the actual device itself is connected to pin 87 now this is the 4 pole normally open style relay..should you have a 5 blade relay the very center blade is normally colsed position and is conductive to post 30 when de-energized..open when energized

any other style relay be it a 3 post is common ground to the case for the energizing coil..if it be a different syle 4 pole odds are the two that conduct with ohm test is the coil (should show slight resistance of the coil) the other two are the normally open contacts that close when energized

Hey Ed,

Is there any chance that you can link us to somewhere we can pick up a DbDt relay, and maybe tell us what blades to the relay correspond to the internal coil and switches shown in the diagram you posted? That's the only component I've never had experience with before.

I wish I could. If I knew that part I'd probably have the thing built by now. I did purchase the supplies from an electronics place. I should have the name of it at home.

HI I still trying to work out one more promblem I HAVE THREE brake lites now and no feed back through the turning signals I put two diodes one in each brake light wire this stop the feed back of the turning signals but now when I PUT on the brakes my parking lights lite up Im thinking that the head light switch is were my problem lies the turning signals feed off the ignition but the brake lights feed off the light switch so IM still working on it ? IM going to try the second brake light wire .I will keep up dated .ED

Ed this is what I was questioning. Because the brake lights are hooked up through the turn signals and the front signals aren't on seperate wires like in a 7wire system they light up with the brake lights.

[Ed Fleming]

young ED MY brake lights get the power off of the back of my light switch.AND my turning signals get there power from the ignigtion.there were only three wires on the turning signals one hot to the flasher and right and one left . The flasher has three prongs one hot and one that flashes and the third one was to go to the hi beam light . This is the instructions I got with the flasher I bought . thanks for all the help ED

[Plymouthy Adams]

third one does not go to the high beam..it goes to the indicator light for the turn signal..the three prong flasher has a NO and NC contact that swith states when active..the turn signal switch itself redirects this wiring to appropriate terminals thus using the power from the stop light switch and activates the selected direction while leaving the unselected functioning as a brake light if and when you brake while signalling.

here is what I think is the simplest way to rig signals. I have done it a couple of times, and thei is what I will do if I ever get to my Bugeye. It does require the use of seperate light fixtures for rear lamps and double filiment bulbs it the front lights. It requires a new wire to be run to new lamps and to the second element on the front lamps, but is is simple and it works.

The dpdt is a double pole double throw toggle switch available at radio shack or most auto parts stores. It will not need to be tied into the brake light circuit as the new lamps at the rear will allow the brake lamps to work and the signals to work independently. You should probably take switched power rather than battery power so they won;t work until the ign is on. Aux terminal will work for power. this is how I have my P15 circuits run, I had to substituted the DPDT for th eboken switch in the add on signalstat type asembly. So i have three brake lights, two running lights and two signals at the rear.

[Plymouthy Adams]

typically you will need the stop light switch, the flasher (two or three prong, your choice) the 3 wire turn signal switch, two DPDT relays, two diodes and dedicated left and right turn dignal indicators if you wish to tap the relay or a single indicator if you wish to use the three prong flasher...use a dual element socket front and rear...you get parking lights, turn signal front and rear where at the rear they will all three light as brake is applied and if you chose left or right turn, the opposite side will light with your third brake as the selected side flashes, if you chose to use the relay to light the idicator off the normally closed pole then you have dedicated indicators left and right and use a two blade flasher...

you do not get four way flashers..as the turn signal switch will not make both connections at the same time..however another flasher, two diodes and switch will get this function for you also

I used the schematic that Ed posted in my '41 P12 wagon using an original Mopar three wire turn switch. Works fine for me. I didn't use the diodes because I have the two bulb turn indicator/high beam indicator on my dash. I also don't have a middle trunk light. The wagon came standard with just a driver's side dual element tail light. The passenger side was optional and needed for turn signals. I added the passenger side light. I also colored the front parking light bulbs orange to make them more noticeable.

Hey Jim, What kind of paint did you use for the front bulbs?

Tom,

I bought some orange tinted paint at a hobby store. Sorry but I forget the name of the paint. I am sure someone at the hobby store would know what to use.

an amber colored medicine bottle slipped over the bulb behind the lens can also be used..

[Jacqualine47]

I found another diagram on the H.A.M.B. forum - but the pinout numbers for the DPDT relays were wrong... I managed to find a correct set of pinout numbers and used paintshop to add them to the diagram.

EDIT:

Oh yeah, and you can get 12v 15amp DPDT relays on amazon.com from a vendor called something like sacramento electronics.

better than double posting

:D:D:eek: try that over here and get busted... that's the kind of stuff the police really likes!

i personally think of it as a very creative and cheap way to get a colored flash light.

if you're running 6V it looks nearly the same, anyway...

Germany had many a vaired rules and regulation concerning cars and modification do's and don't that really tied your hands and this was back in the early 70's while I was in Bavaria for two years...I can only imagine they are getting more and more stringent as even here in the USA it is getting more that way...but only thing here is I see a ton of violations weekly it seems and nothing is ever done to enforce the rules.

I have a few applications here at work with smaller lamps and the need for color changes whereas the bulb is clear only the pliable transparrent color caps is fitted per application

the need for other colors like clear back up light, red brake light lens and the amber trun lens has prompted a varitey of Duct Tape colors...I hear they even have it in camo for the southern population and for the northern boys, it can be had in rust and primer gray combination..

Interesting that states and other governmental agencies are requireing a retro fit to amber lights. I don't believe amber was mandated federally here till 62/63. Any thing before that would have been clear lights with clear lenses. Mine flash white, and the law is written to grandfather that in just like the single rear brake light.

So is it law or just what the constabulary/inspectors thinks it should be. My 60 Austin Healy still has white front marker /signals front, and red stop and run on the rear with seperate red signals.

[Plymouthy Adams]

not just sure when US mandated lenses etc but I do know I illegially fitted my Porsche with European lenses so as not to look like the ugly USA versions..and yes I knew it was not right and no I was never stopped or questioned..would I do it again...probably..to get the right look and as long as they were not an hazard to other motorists.

Thanks too all who help me with the wiring prombles I have them working all most perfect I elimated the front parking lite promblem buy putting two more diodes in the turning signal wire .This elimated the parking lights from coming on when I applied brakes so now I have three brake lights an a faint turning singal light when Im applied the brake put I have a good singal when I not on the brakes , the front works perfect .So two diodes in the brake lights wiring got me the three brake lights and two on the turning singal wiring elimated the feed back in the parking lights. I think I have to get a new turning signal unit .for mine has only three wires and its worn out and has the old wiring Thanks again for all the help Ed
