Here's the problem.
A "pop" then all, I mean all, electrical went away. Full power at the battery but none anywhere else. Actually a little, enough to barely power the inside lights for just a second and then dead.
Walked out this morning and the batter registered 12.4 but it fired right up. I turned it off and came in to the office.
Is there a thermal electrical thang somewhere in Chevelles. Obviously I cannot trust going anywhere in it until it is found and fixed. Reliability is way high up on my list of happys.
There is a pigtail wire that comes off of the positive battery cable that goes to the junction block mounted to the radiator support. This wire is a fusible link, made to blow if there is a problem in the charging circuit. Check that the wire is secured tightly to the junction block, you'll probably have to take the battery out to check this. The horn relay is mounted on the left (driver's) side of the radiator support. The power to the fuseblock comes off of the wires from this relay, and there are also fusible links here. Check to be sure that the terminals are clean & tight on the relay and that you have battery voltage at both of the big lugs on the relay. There is no thermal thing anywhere in the system. You should probably buy the 1968 Chassis Service Manual and the Assembly Manual for the car. It will give you the information that you need to fix a bunch of problems.
