Driving my roadster yesterday and heard a pop and seemed to smell smoke. Engine quit and towed car home. Hope to work on it this weekend. EZ wire harness for two years. What should I check? Where to begin? Ideas! Posted using the Full Custom H.A.M.B. App!
Just search with a good flashlight the harness under the dash ,closly at the ign area.If it smoked you will see wrinkled wire.
-Check to see if you have 12+ volts at the battery. If you don't have a volt meter, get one with an audio continuity setting. ($25 or so and up). Make sure you have a good ground for black volt meter lead. -Test again at the starter battery cable (or the remote solenoid). Be looking for wires connected to power cables that could run to key and fuse panel. -Check for power to the key switch and any circuit at fuse panel. If there is none, you might want to check for blown fuse in panel, indicating which circuit might have shorted fusible link in supply wire to panel. If you find a problem fuse, you might want to lower it's amperage, so that it blows without taking out the supply fuse next time. No obvious problem, you might think about making notes about the fuses and pull all of them out while you find the panel supply and key supply wires. If you have power at one end and not at the other, there is probably a fusible link or maxi fuse blown in those lines. You can test wire continuity by touching both ends with the volt meter leads while on the audio setting. If it makes the beep, wire is carrying current. Once you get always hot power to the panel, you can start putting fuses back in, one at a time, largest first, in hopes of finding the shorted circuit. Then, remedy the short by replacing the wire or whatever you have to, OR, leave the fuse out and test that the other circuits work. -If there is power to the key switch, test voltage at coil+ with key on and off. No power to coil, check for ballast resistor between key IGN and coil+. There should be nearly the same voltage going in to resistor as there was at the battery and probably somewhere near half the voltage coming out toward coil, if it is a point distributor. No resistor in line, full voltage at coil+. Other side of coil must ground out as points close. -If you have power to coil, check for spark at plugs. -One of the wires to alternator or voltage regulator should be hot. -If you have amp gauge, one side will be hot. Volt gauge will power up w/ key on. -Put inline fuses in any unprotected circuits -Let us know what you find
