Had an interesting happening yesterday while on a wonderful Northern
Calif Sunday drive in the '62 MKII Sprite.
I literally "FRIED" a tach cable. The rubber coating melted (smoke
too)
How can this happen? I had the tach cable routed from the generator
rear end gear assembly back to the heater box with a gradual right
angle turn to lay between the heater box and the battery with another
gradual right angle turn to the firewall and through to the tach. The
cable fried from the heater box turn to the generator area like it got
"electrified" somehow and had a direct short. I suppose the rubber on
the cable had rubbed through at this turn creating a ground. (I have
a negative ground system) But that means the cable itself had to have
a "positive potential" from the generator, Right? How can this
happen? Is the generator FRIED as well causing this? The generator
was VERY HOT to the touch. I did read 2 volts to ground from the
large spade terminal on the generator with the leads disconnected and
the car running turning the generator at idle. Is this correct?
Diagnosis and help appreciated on this one. Don't want to FRY another
anytime soon. (Can the local auto parts house bench check my
generator correctly?)
