New to me 1977 Cobalt 19CD, came with a mercruiser 260, which blew up sometime in the 80s. Original owner dropped in a 5.0 GM crate motor. Taken it out a few times, runs great. Does hiccup at higher rpms but I attribute that to the old gas in that 50 gallon tank.
End of the day at the lake and I am idling up to the dock with the blower going and every other electrical thing humming, nav lights, radio, interior lights, when I catch a scary rubber melty smell. I killed everything and went to investigate with a flash light. Wires were warm under the dash but nothing was on fire and the boat ramp was crowded so I loaded up quick. Came home and to recreate the event I turned everything on again. Within a minute the blower wires were hot to the touch. Nothing else had even warmed up yet.
The blower seems to be churning along nicely, isnt lugging or anything and doesnt seem to be pulling too many amps and hasnt blown the ten amp breaker. Though it is an old breaker.
Hunting down the grounds, battery appears to be hooked up to the copper plate on the back, instead of the motor like I thought it would be?? Probably going to replace the ground wire off the battery, it looks terrible and is loose.
Thoughts?
