VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1933-1936 1936 Voltage regulater

Ok, I have another questions for the Chevy gurus out there....I've checked the forums and have heard it mentioned that Chevrolet did not have voltage regulaters in 1936 cars. Well, my 1936 Master coupe has one on the firewall above the steering column. Was this an option? Why would you put one on if the car has a cutout?

The 1936 Chevrolet with the production generator did not have a voltage control.(Canadian cars did)...There were optional higher output generators available that did require a voltage control.This was mainly for police and heavy duty applications.The 1938 Chevrolet was the first to have a voltage control as standard equipment.First three unit voltage regulator was used in 1940 along with a two brush generator.
It was rather common to replace the 1936 generator with either a 1938-38 higher output generator and voltage controll or install a 1940 two brush generator and voltage regulator for high amp out put.
In so doing the max. amps would be increased from the 20 amp range up to 30 or 35.What number generator do you have and is the a number stamped into the base of the regulator?

Hi Gene. My generator is a 935V. The regulater is a "Blue Streak" not Delco-Remy so I know it has been replaced. NO #s I can find on it. It has 2 glass fuses top and bottom on the outside. Thats about all I know. The car has no radio or foglights or other accessorys that would require a higher output. What do you think?

935V is a 1935-36 Master generator.It did not use a voltage regualtor.There would have been a cut-out mounted on top of the generator.The generator would charge at one rate and the rate could be increased by pulling out the light switch knob 1/2 click (between off and parking lights).The Standard did not have this feature.
I have never heard of it but there may have been a way to convert this generator (by grounding or un-grounding the fields?) and use it with a voltage regulator.
What leads me to think this is possible is that the instruction sheet that came with a Delco rebuilt generator for 1929-39 (was a 1939 type generator) has instructions for using that generator,which was designed for a voltage controll, on the older models that have a cut-out.For the older models they said to ground the field terminal and decrease the charging rate by adjuting the third brush.This would cuse the generator to charge at a steady but lower rate....perhaps the reverse of this could be done with a 1936 generator---???---so a regulator could be used.
Is the charging system operating OK now?

Hi Gene, thanks for your response. Yes, It seems to be charging fine. It does have a cut-out mounted on top but, it is not a delco-remy it is smaller with a cadium finish I think aftermarket. The ampmeter shows a good rate of charge (positive) when the engine is running. Im also using a 8 volt battery.

Is the voltage reg. a headlight relay?

I dont know......

Trace the wires and see where they go.

:) :grin:

Down here in Aus. we had relays from 1935 std models. The last cut out on the generator was 1934

Thats because they shipped Canadian cars down to you guys....you know-keep it in the family :)

Or disconnect the wires and see what dosen't work.

Yes I found that it connects to the dimmer switch.. Im taking it out. But my system is not charging and this regulator has nothing to do with that. I show a discharge and I think that I have the wrong generator in it. I put in a 36 truck and hooked two wires on the gen side and one on the "batt" side of the cutout. I think that is wrong. I do have the 935 gen and it has three teminals: one big stud and two on the cutout. How should a 1936 generator be hook up?
