Re: Dimming lights, altenator or battery?

Whoa, I am I missing something here.

Andy you say that a 760 watt converter draws up to 63 amps? And he is running it through the stock cig lighter? I think stock wiring for the lighter is 12guage 20amp maybe even smaller.

If that is the case you need to upgrade your wiring. The main power wire that goes to the cab is only 12 gauge and that has to power all accessories. I think you are asking for trouble by running it through the lighter. Try hooking the convertor direct to the battery and see if you dim lights go away.
