Normspeed Posted November 25, 2007 Report Posted November 25, 2007 Check this overdrive lockout switch. I can flip it with my thumb as I shift for that 5 speed effect:D It has the added advantage of rating at least a 9 1/2 on the crude & ugly scale! And someone might even mistake it for a nitrous button. No relay invloved, just a 10 amp switch and 14 Guage wire all the way. It interrupts the circuit coming out of the rail lockout switch to the governor. Quote
jd52cranbrook Posted November 25, 2007 Report Posted November 25, 2007 But can you kick down with it? Wait,, duh,, thats why its there. that does looks sleek tho,,,,,,can hardly tell its even there..... Quote
blueskies Posted November 26, 2007 Report Posted November 26, 2007 Check this overdrive lockout switch. Stealth! It's the "gitterdone" switch... I like it. Wonder if it'll bite-ya if your fingers are damp? Pete Quote
Norm's Coupe Posted November 26, 2007 Report Posted November 26, 2007 Norm, I think Pete may have something there. If you touch both wires, or just one and any metal on the car at the same time, you may get more of a charge than you think. I'd cover those bare contacts with some heat shrink or electrical tape. If you had a ring (or a metal watch band) on and it made contact with both contacts you'd not only get a good charge, but could short out the system. Or, at the very least turn the OD on or off when you really didn't want to. Quote
BobT-47P15 Posted November 26, 2007 Report Posted November 26, 2007 Looks like a dad-burned aeroplane thing...... Quote
Normspeed Posted November 27, 2007 Author Report Posted November 27, 2007 Will 6 volts right off the battery give me a shock if I touch both posts? Yikes! I'd better get some duct tape on that puppy pronto! Quote
Heavy Flat Head Posted November 27, 2007 Report Posted November 27, 2007 Norm, That is class or is it ?. Quote
Plymouthy Adams Posted November 27, 2007 Report Posted November 27, 2007 only time I have ever been shocked by a car battery is when I was soaking wet with sweat..moisture plus the added value of salt will tingle you a bit... Quote
Merle Coggins Posted November 27, 2007 Report Posted November 27, 2007 6 volts wouldn't hurt. Even 12 volts is only a tingle. But 24 volts will get your attention Quote
Plymouthy Adams Posted November 27, 2007 Report Posted November 27, 2007 I read where the auto industry may eventually go to 24 volts. (I'd believe 28 as used in military). smaller lighter weight components..common buss for the electronics..kiss the fix at home goodbye for sure... Quote
greg g Posted November 27, 2007 Report Posted November 27, 2007 Oh wait till they get to single wires carrying different power to different loads at different frequencies. Multiplexing??? I think commercial air craft are going 48V halving wire size again. Quote

Tim, my mechanic friend told me the same thing a couple of years ago. Think he even mentioned a possible date for the switch to 24 volts. Said it will allow them to handle more electrical gadgets.

TodFitch Posted November 27, 2007 Report Posted November 27, 2007 Tim' date=' my mechanic friend told me the same thing a couple of years ago.

Haven't heard much on that in the last few years. There are some cars with high voltage in them on the road today: While the lights and accessories on our two Priuses are 12v, the traction batteries are around 300v. That would be enough to put you back a bit if you came in contact with it. All the high voltage/power wiring is protected with an extra bit of tubing in a nice bright orange color to protect it and to warn you to be careful around it. It would be perfectly feasible to run two wires (bus) around the car that provides power and have control signals imposed on it to turn on/off or otherwise control the loads plugged into it. The units plugged into it would have a small controller that would decode the signals and respond. So, for example, a right rear tail light controller would plug into the bus and look for and respond to any on/off commands addressed to any right rear light units). For after market you could just plug in a bunch of light units and they would all come on at the same time. In some regards this would make modifying and/or repairing the system easier than with all the spaghetti we have for wiring today. Given the decreasing cost of electronics and the increasing cost of copper wire I would be surprised if this type of automotive electrical system were introduced in the near future. Quote
Merle Coggins Posted November 27, 2007 Report Posted November 27, 2007 I've been dealing with 24 volt systems for years in heavy equipment. I've also heard that the auto industry would be going to 48 volt or higher to run electric servo steering and brake systems that can be computer controlled. A complete drive by wire vehicle. I don't know when or if that will ever come about, but it wouldn't supprise me when it does. And yes Tim, 300 volts would knock you on your @$$ PDQ Quote
