Wireing issues

Hudsonrules

:eek:Trying to put the '37 Terraplane back together and have a problem with wireing. I need some advice please. This car has a later generator and regulator probably '51-'53. I hook the battery cable to the solonoid along with what appears to be a wire to the ignition switch and a second wirer that should go to the battery, but it does not appear to. No current to the ignition switch or light switch. However, the wire at the field terminal on the regulator is hot, I thought it was to go to the generator, it is not going any where right now. The battery terminal is hot also which it should be. the wires are not touching. Of course things have been changed in this car during the past 73 years. Where is the fuse block? I have not found it yet, but I will keep looking. Thanks for any advice and help in advance. Arnie in Nevada.

The only "fuse block" will be on the light switch (at least, if you have the original light switch). It has two fuses, both for the lights. Beyond that, you will have in-line fuses here and there.



Have you compared your wiring with that of the '37 wiring diagram?



Not sure whether your later regulator is correctly mated to your later generator, of course. In my '37, there is a '38 generator (someone else put that in) and I have the 1940-49 Hudson regulator, which works quite nicely. I checked it out and the combo is supposed to be "okay". But all my wiring correctly follows the wiring on the diagram. I would think that yours ought to, as well.

You do need to make sure you have the right regulator for the generator you are using, and unfortunately there are too few auto electricians who are still knowledgeable about such things.



You will also need to make sure you follow the stepdown charging circuit diagram for that portion of the wiring rather than the terraplane circuit.



For fuses I normally use a modern fuse box with 4 blade fuses, they are small and easily kept out of view if you prefer.
