I think the heavy rain has shorted out a wire someplace on my stock 74 REPU. Last night the headlights went out (everything else seems OK) while at Home Depot. Found that the 25amp fuse (2nd from the firewall) was blown so I ran back inside HD and grabbed some 25amp slo-blows to get back home (about 10 blocks). But they kept blowing, quicker and quicker. And they're very hot. They blow out as soon as I go to the first position on the light switch to turn on the marker lights. So I suppose it's in the marker light wiring, not the headlights.
Anyone seen this before?
Is there a wiring diagram someplace on the internet?
