So I have a 98 5.7GS; just put a new longblock in and got her in the water yesterday.
Before I put her in she idled in the driveway for an hour no problems.
I put her in and we ran about 5-6 miles at moderate speeds then the engine cut out and would not restart.
About an hour later I tried it - she fired and ran about for a few minuites - same thing.
When this happens the voltage coming into the altenator is 12 volts - the voltage coming out is 6 volts, the atl is hot, the back of the ignition switch is hot as h*ll, the back of the voltmeter is hot; and the ignition fuse got so hot the plastic melted.
Does this seem like concidential timing and the voltage regulator is going out? it is another wiring issue angering it?
note when this is going on there is no spark and the voltage meter on the dash is reading under 10 - when everything cools off ~ 1 hour sitting the voltage meter on the dash pops back to 12 and the engine will immedieatly start. HELP
The alt is a volvo/ mando 3856600
