My taillight/instrument light fuse keeps blowing. It never happened before. I took a sharp turn last night and it jus stopped working. I tried replacing it with a 10, 15, and 20 amp fuse.

When i just let my car sit there its fine, but when i start driving , the fuse just blows
What should i check?

 

I would get a hold of a helms manual and check for grounds. Also check the wires to see if they are warn and shorting out.

 

Do not use larger fuses. You run the risk of overheating the wiring and increasing the severity of your problem.

Do you own a multimeter?

 

I got a multimeter....where should i start ? Last night i put in a fuse and my lights worked for like 20 mins.......now they blow instantly every time i replace it.

its my tailight/cluster fuse, and its not my radio cus i disconnected the whole thing and it still happneed

 

Unfortunately you have one of the worst electrical problems to diagnose: intermittent. Does the car have an alarm? If so, I would look at the relay that controls the parking light output first. Check for grounded hot wires.
