trying to install 100 amp system in M38A1, can't figure out leads #10 and 12. they should be batt supply, and ignition. Where do they tie in to system? Dave, N2XYP, sfc e-7, ret.
The number 10 wire is spliced to the number 10 wire at the connector for the original generator regulator, and the number 12 wire goes to the number 12 wire behind the instrument panel. I have the installation manual if you need it.
