Iıve been off the gmclist for over 3 years. Being retired keeps you busy.

About to make a trip to Texas to wrap up storm damage repairs on the family
home
Thatıs taken two years to work thru since I can get loose only for a short
period in the Summer.

Coming home from a rally, I lost lights when it started getting dark.
Turning on Head Lights blew 3 fuses - dash and exterior lights
(head lights themselves are ok). I got home just after the sun set.

Repeated the problem several times with new fuses. Looking at the MHıs
wiring diagram, I suspect a bad headlight switch.

Browsing located the GMC Motorhome Photo Archive and some searching
stumbled across jharpers ³Headlight switch removal/replacement (How to)²
Photo Essay from 2004. Wonderful.

Is there a check of the switch I can make that can exclude it as the cause
of a short in the system without pulling the switch?

The wealth of information this community has assembled over the years
continues to amaze me.

Thanks,

JohnM
