There are 11 fuses in this auto. Can anyone tell me the fuse size, where they are located, and what their function is? I know this is asking for a lot, but sure would help when one is troubleshooting wiring.
Just auto sitting, I had one wire burn up which went to a fuse and then to the park switch and solenoid I believe. Not sure why it would have burned up since there should have been no voltage on it. But not
too sure of the wiring since wiring diagrams etc are pretty bad in this era. But some of you might have researched.

So, one of the number one culprits with these old geezer cars are the battery cables which were ruthlessly changed out by unsuspecting (un-knowledgeable) DIY backyard mechanics. Six (6) volt systems require massive battery cables 00 or 2/0. Someone, in the past, might have changed battery cables to 12V sized battery cables resulting in numerous wiring issues. Not the least of which could be the burning up of wiring. Firstly, ensure you have 00 or 2/0 battery cables and ensure the negative (00 or 2/0) cable is securely fastened to ground. Clean the ground wire attachment point to ensure it is solid metal-to-metal contact.

After posting the above...someone correct me if I'm wrong, but the battery cable should go directly to the starter solenoid with nothing between the battery (+) terminal post and the starter solenoid. If per chance someone placed a cut-out switch between the battery (+) terminal post and the starter solenoid (e.g. a previous owner?) - that is incorrect. Any switch (e.g. cut-out switch) should be wired after (from the starter) - not to the starter. Using 12V battery cables on a 6V system yields an enormous voltage drop. Again, ensure you have the proper 00 or 2/0 battery cables with the (+) battery terminal cable routed directly to the starter solenoid.
