[QUOTE="larryshoat, post: 474301, member: 6773"] I checked one of ours the white wire should be dead with the key off. There should be a wire from the switch to the gen light then from the gen light to the white wire on the alt hookup. When the alt starts to charge the white wire loses it's ground from the regulator and the gen light goes out. Sounds to me like that switch is bad. That's a good idea about connecting between pos cable and post. I just use a test light , most of those meters are so sensitive they will pick up voltage on one that is working right. Larry [/QUOTE]
