nice info thanks!

84 Corvette problem. I pulled the fuse that was causing the draw. However, there are over 12 circuits on this fuse. How do I find which circuits is causing the draw?

Hello i been try this, still can't find what's short... Do you have any other idea about shorts circuit?

[@chrisb7528]

A drain on a battery isn't a short, a short can drain a battery but it can blow a fuse, start a fire etc. I assume you don't mean a short to ground bu a parasitic drain.

1. Use a thermal imaging camera. I know they are pricey.

I tried this and my test light did not go off. I have a diesel truck with two batteries so I completely disconnected one battery then tried your method. But no success

[@toddwood1150]

Your issue would then be on the constant hot side of the fuse panel. Problem would be with something like your starter or charging circuit... alternator etc. I see this was from a couple of weeks ago so I hope it still helps.

@toddwood1150 Thank you for replying. I'll check it out see if works

[@freespirit369-nb4jf]

I don't get it? Aren't you just completing the circuit again? Battery cable off connect test light to cable , light to post completes circuit again.🤔

[@HVAC_Mechanic]

If the light is on, something is draining the battery. Pulling fuses one at a time until the light goes off will often point to what is causing the drain. For example, if you pull the tail-light fuse and the light goes out, then that is where the problem is. Be sure it is not an open door, dome light, or something similar.

@@HVAC_Mechanicjust to make sure I got the right tool. I got a “circuit tester” but is that a “test light”. Are they the same thing
