AzBob Posted March 4, 2015 Share Posted March 4, 2015 Just did a search for correct wire gage sizes and didn't come up with much.My existing generator wire (generator to ammeter) appears to be 12 gage from my measurements. Can anyone verify this? Link to comment Share on other sites More sharing options...
Larry W Posted March 4, 2015 Share Posted March 4, 2015 I would measure the existing wire diameter with a micrometer or vernier gauge in several places and take the average to compare with a wire gauge table found online. Link to comment Share on other sites More sharing options...
Bhigdog Posted March 4, 2015 Share Posted March 4, 2015 A google search of stranded wire size will answer all of your questions..................Bob Link to comment Share on other sites More sharing options...
Ben Bruce aka First Born Posted March 4, 2015 Share Posted March 4, 2015 Bob, my car is 25 years newer than yours, but the wire in question is 10 gauge, per shop manual. 12g would probably have been enough in 1925. But I see no reason you can not use a 10 Gauge in its place. Ben Link to comment Share on other sites More sharing options...
AzBob Posted March 5, 2015 Author Share Posted March 5, 2015 First Born, Thanks for the generator wire gage size! Am in the early stages of rewiring and using the generator wire as a reference, I can determine the gage size of the other wires. I went through the 1926 Shop Manual and Reference Books but couldn't find any information on wire gage sizes.Larry W, thanks for the tip in regards to measuring the wire in several places then averaging the measurements.

jvelde Posted March 5, 2015 Share Posted March 5, 2015 Here is a diagram for '38 which should give you some help. Link to comment Share on other sites More sharing options...
AzBob Posted March 5, 2015 Author Share Posted March 5, 2015 John V.Thanks for posting the 1938 wiring diagram. I see it has the wire gage values as well as the wire colors and markings, very helpful. The 1926 shop manual wiring diagram has none of that information.

jvelde Posted March 5, 2015 Share Posted March 5, 2015 Hope you can compare to your wiring and maybe the color codes are the same - that really wouldn't surprise me. Link to comment Share on other sites More sharing options...
hidden_hunter Posted March 6, 2015 Share Posted March 6, 2015 Hope you can compare to your wiring and maybe the color codes are the same - that really wouldn't surprise me.there was no color coding on the wiring in our 1926 generator, just crumbling off insulation Link to comment Share on other sites More sharing options...
DonMicheletti Posted March 6, 2015 Share Posted March 6, 2015 The '38 generator puts out more current than your '36 so that wire would be OK. On something like that - bigger is better Link to comment Share on other sites More sharing options...
