HEI Distributor Wiring

I'd recommend a high impedance meter so that not too much power is taken off the wire when you sample it, which could make the voltage reading lower.

I am pretty sure it is 12 gauge wire. It's almost as big around as a pencil. I will double check the voltage when running. Maybe it's my imagination but it seems to be running even better now.
