My little brother has a 1992 Isuzu Amigo. Its always been a POS since he got it ... Hardly ran, poor mpg, trans acted weird. I worked my ass off cleaning this, draining that, blah blah blah... Then it quit starting, it quit charging, AND it would do all kinds of neat crap like the lights would stay on with the switch off. None of the problems with the start/charge system were bad enough until this point to actually put a meter on it. The alternator wasn't charging... Crap... Starter wasn't starting... Hmm....
The grounding cable for the battery was just stuffed in the crevice between the AC compressor and the block. Attached the ground cable to engine block.
All problems solved.
That was my morning...
The clutch went out on my 1992 Ford F150. I limped it home, and started pricing parts, tried to sell the truck for awhile and didn't want to let it go for $200 so I pulled the inspection plug a month later.
Mice had built a nest in it and their nest got into the clutch housing. So a piece of coat hanger, and my mom pressing the clutch and bumping the starter, and an air compressor.... I cleaned out the mouse nest from the clutch and problem solved.
Any stories of your "easy" fixes to share?
