Charging System Troubleshooting--Blown Ignition Light Fuse?

Alright, I'm now betting on the tach.

As I recall, there was a similar issue years ago on some CSX cars. I believe it was determined the problem was in the ignition light housing. Blas

Thanks. I’m pretty sure I already eliminated that as a possible cause, but I don’t really trust any troubleshooting I did with the voltage stabilizer installed.

I’ll try it tomorrow, but I’m skeptical. I had the tach out of the circuit when I was blowing fuses last weekend.

I’m betting on the fuel sender, the troubleshooting of which was masked by the voltage stabilizer in the circuit.

Hopefully one of us is right!
