I have both the block and firewall grouns connected but cannot find the frame ground. Can someone post a picture of where it should be located? Thanks!i can't tell you the stock locations- but i can tell you that more is better.
ground to frame
ground to block
ground to firewall
then ground is not your issue,or light would not come on when mounting regulator...My alternator light keeps coming on, but only when I mount the voltage regulator (brand new) to the rad support. If the voltage regulator is hanging in mid air it's completely fine.
