Hello everydoby ! I am from Italy and I've been owning a 1954 Chevy Bel-Air for almost 20 years. It runs and always run great. The only problem I had over the years was with the VOLTAGE REGULATOR.
I've got a 6 volts system, and every know and then I need to change the regulator. I put a new one..it runs ok for few months, maybe a year and then...stop...I need to change it.
Please, any idea ?? Any suggestion ? Thanks a lot ! Alberto

Hello Alberto! Welcome to Chevy Talk. I've not much to add, except to say that I think these voltage regulators should run for a very long time without needing to be replaced. Just to be certain we are talking about the same part--take a look at this image. The voltage regulator is labeled. Is this what you are using? An original voltage regulator?

Hi, yes this is the part I am talking about.
I don't know...at the moment I've got a new generator and a new battery.
I put a new regulator...it run fir a while, and then stopped to charge..

So does stopped charging mean that the ammeter is not showing a charge or that a check of the system shows there is no charge. My question would be is the generator charging. Did you do a polarity check after installing the generator?

Yes, I can see that there is no more charge cause the ammeter stops to show the charge..and I also can see it looking at lights.

I've never done the polarization procedure on my '54, as I believe my car uses an alternator. But I am told that this procedure can be very important for a generator. I am sure someone here will share the procedure with you. I think it is in the service manual as well. That might be the problem. There really is very little to fail in these regulators.

Section 12 page 19 of the 49/54 shop manual says"To polarize the generator momentarily, connect a jumper wire between the generator terminal and the battery terminal of the regulator before starting the engine". I just hook one end up and on the other end of the wire touch the other terminal, a spark is all you need.

Yes, I also made the polarization..infact at first the Regulator works properly.

I can see the ammeter working and the lights icrease. The last one I put on the car worked for about 2 months and then stopped to work.

I really don't know...in about 20 years, I changed maybe 10 regulators !

The strange thing is: I put a new regulator, and ok, everyhthing works. After not much time, the regulator stop to work. I never understood why...

Thanks everyone for your help, anyway...

I wonder if you have a earth fault . Do you have an earth wire to the body ? I would recommend one ,The voltage regulator earths though one of the mounting screws to the body in most cases , check the back of the regulator in this location and remove any paint also fit a star washer between the two ,l run a earth wire from the body of the generator to the mounting screw of the regulator ,Earth connections are often over looked but you cannot have to manny, Cheers Stuart

Hi Stuart,
I never had a ground wire connected to the Regulator.
I recently saw a pic with this kind of wire, so I connected one (from ground to the regulator screw).
I've got a spare/new regulator. Do you think I can try to put it on ?
Maybe with this wire the regulator will run correctly...

I will check, thank you.
So, there should be a wire from the battery to the body and /or a wire from the engine to the body...correct ?

ok, thank you.
I am going to check it how it is, and maybe take pics, so I will show them to you.
Thanks again. Alberto

Hi, it looks like I am not able to attach pics...

Anyway:
1) Negative of the battery is connected to the body, with a proper wire;
2) Negative of the battery, also connected to the engine (to the water pump).

I would like to put a wire like you told me, directly from the generator to the regulator. Please, where did you connect the wire on the generator ? I see two bolts: one to the A(rm) and one to the F(ield).

Note that there was two different voltage regulators used in 1954....and two different generators.

  • Gene_Schneider Said:

I'm actually seeing 5 different combinations:

Standard Equipmwent:
GENERATOR 1100028, VOLTAGE REGULATOR 1118843, 40 AMP, Standard Transmission

Regular Production Option:
GENERATOR 1105009, VOLTAGE REGULATOR 1118831, 40AMP, All except Convertible
GENERATOR 1102793, VOLTAGE REGULATOR 1118827, 45 AMP, All and Corvette
GENERATOR 1105008, VOLTAGE REGULATOR 1118835, 50 AMP, All except Convertible
GENERATOR 1106976, VOLTAGE REGULATOR 1118942, 55 AMP, All except Convertible and Power Steering Optioned Cars.

I do not know, however, if mixing these would cause a Regulator to fail.

Hi,
I bought mine from Chevs of the 40s.
It's a 45 amp and should be ok for my car (1954 Bel-Air 2 door sedan).

Thanks anyway.

ok, I am going to connect this wire directly from the generator, like you say, to the regulator.

Let's see. Thanks everyone for your nice help.

I will inform you about the result.
