Hello
I have a 1979 Four Winn's with a 470 Mercruiser engine. I have the GM 1 wire conversion kit for the charging system. At idle it charges at 14.2 V. I checked the voltage at different points on the engine and I get very different readings. The electric choke has 13.5 while the wire to the coil is only 11.5. I know that the purple wire is a resistance wire , however I don't know what the voltage to the coil should be. Im not having any trouble currently and would like to keep it that way. Is this normal voltage or do I have a gremlin lurking somewhere...any thoughts?
