Reg Evans Posted July 28, 2008 Report Posted July 28, 2008 Shouldn't the generator be putting out a little over 7 volts. J.Lo's engine is running at about 1000 rpm in this photo. EDIT......15 minutes later...I just checked the gen in another 6 volt car and the meter shows 7.7 volts at about 1000 rpm so I guess J.Lo's gen got fried last week when the manual starter switch developed an internal short. The other part of the problem is that the amp gauge does not move when the lights are turned on or the brake pedal is applied even though these lights are working. This car was rewired and a fuse block was installed. All the fuses are OK. Quote
greg g Posted July 28, 2008 Report Posted July 28, 2008 I think 7.5 is the deal so on that scale you are probably OK. Quote
Reg Evans Posted July 28, 2008 Author Report Posted July 28, 2008 Greg. I just edited my earlier post. I hooked this meter to my 35 Dodge and at 1000 rpm the meter shows 7.7 volts. The amp gauge doesn't move when the headlight or brake lite are switched on so I guess I have multiple problems. Quote
steveplym Posted July 28, 2008 Report Posted July 28, 2008 Have you tried to polarize the regulator yet? That has happened to me before especially when the system shows 0 on the amp gauge. Quote
Don Coatney Posted July 28, 2008 Report Posted July 28, 2008 Have you tried to polarize the regulator yet? That has happened to me before especially when the system shows 0 on the amp gauge. Regulators do not need to be polarized. Only the generator needs to be polarized. But it is polarized at the regulator. Quote
steveplym Posted July 28, 2008 Report Posted July 28, 2008 Regulators do not need to be polarized. Only the generator needs to be polarized. But it is polarized at the regulator. Thanks for the correction Don. I never can remember which terminals to touch and which item is actually being polarized. As long as I remember never to touch the field wire looks like I'll be alright. Quote
Reg Evans Posted July 28, 2008 Author Report Posted July 28, 2008 Well...I have a special problem there. I was going to try that until I discovered that the cheap decal on the top of the reg. had faded and the locations for Batt, Arm, and Fld are not visible anymore. Quote
steveplym Posted July 28, 2008 Report Posted July 28, 2008 Can you show a picture of it? I'll have to look at the two regulators I have, but I'm pretty sure one is just like in Don's picture and the other one has the field terminal on the opposite site of the rest of the terminals. Quote
Chester Brzostowski Posted July 28, 2008 Report Posted July 28, 2008 Reg, If you need a generator I have three lying around. One I rebuilt awhile back and it passed the bench test. No warranties implied because I never installed it in the car. I have since gone to a 6vdc alternator. Chet... See post from 2004 http://www.chetscoins.com/1948p15/20045/Generator.htm Quote
Reg Evans Posted July 28, 2008 Author Report Posted July 28, 2008 Now to confuse matters more here's a 3rd alternative for polarizing a generator ] Here's what the regulator looks like in my 42 Dodge Quote

Reg Evans Posted September 9, 2008 Author Report Posted September 9, 2008 I just wanted to publicly thank Chet for his generosity. He sent me a good generator and regulator for the cost of shipping only!!!! Here's to Chet.....3 Cheers !!! I hope I can return the favor sometime soon Chet. Thank you, Reg Quote

slategrove Posted September 23, 2008 Report Posted September 23, 2008 I found this thread when searching for a problem I'm having currently... Just got a new voltage regulator and put new brushes in my generator, because I'm not getting any charge...I polarized the generator and while running I am only getting 6.7 Volts...I know it should be 7.5 by the above posts, but am wondering what to do next??? Thanks in advance, Slate Quote
Normspeed Posted September 24, 2008 Report Posted September 24, 2008 Have you run the test that temporarily takes the regulator out of the picture? It's easy. Quote
slategrove Posted September 24, 2008 Report Posted September 24, 2008 Normspeed, No I haven't, and I don't know what that test is...can you enlighten me? MAN, this generator thing is frustating!!! Quote
Normspeed Posted September 24, 2008 Report Posted September 24, 2008 Run a jumper from the field terminal on the generator to ground. Run the engine at 1000-1500 rpms. If the gen is good you should see your ammeter reading a full charge. Which is the field wire? My 53 Plym manual shows the field post using a 16 Gauge green wire while the Armature post hooks to a much heavier 10 gauge red wire. The Armature post likely has a larger diameter to accomodate the heavier current flow. So the jumper goes from the smaller (field) post to ground, and only for as long as it takes to run the test, don't leave it hooked up for long periods or while driving. Hope that helps. The good part is, once you get these systems working OK, they are bullet proof. Quote
