help! gauge fues blows when i hit 45 mph

[moe]

i,m running out of options ,since my tack also stops working when the fuse blows ,is it possible it has something to do with distributer or its components . i can drive 35 to 40 miles an hour and no problems but once i hit around 45 mph it blows . the alternator is ok every thing else looks tight . its a 1980 corvette l48 auto with HEI distributer

If the vehicle has a lock up torque converter, try unplugging it at the transmission and see if the fuse blows again.

It's your torque converter, not your transmission, but when they break down they usually contaminate the transmission at the same time. Seen it more than once.


Enjoy the summer.

Maybe the TCC solenoid is shorted.

Maybe the TCC solenoid is shorted.

I would vote for the TCC solenoid too. No current goes to the torque converter just to the solenoid.
