Guys:
On my 1984 M1009 I have faithfully followed everyone's recommendations for cleaning up the electical system including:
1) Cleaning and policing up the fuse block - all new fuses to spec.
2) Filing (i.e brightening the metal) and reconnecting the grounds at the front driver and passenger sides, and inside the cab just above the parking brake.
3) Insulating the harness leading through the firewall (could not see if it was chafed but it was laying on top of a metal seam which was part of the heater mechanism).
4) Cleaning the blackout and service light switches (pulled off the connectors, filed, cleaned and sprayed them down, then reconnected)
5) Replaced dimmer switch on column (that now works)
Here's my issue: I keep blowing the 30 amp unmarked headlight fuse (item #7 on the fuse box schematic frequently posted here).
At idle the headlights WILL go on, and also the high beams, and the tail and turn lights work fine UNTIL I get 1 couple hundred yards down the road and the fuse goes pop. Then I lose headlights, turn signals and flashers. Bottom line: I can't legally drive the thing after dark.
With a fresh fuse in it drives fine: flashers, brakes, etc. But while driving as soon as I put the headlights on the fuse will pop.
Not sure to do next other than crawl into the fetal position. Any ideas?
Thanks in advance
