Car is a 98 Civic EX with a OBD1 LS swap. Has a EM1 gauge cluster. I keep blowing the instrument light fuse under the dash. The recommended amp fuse is 7.5, but the 7.5 would blow as soon as I plugged it in, so I bumped it up to 10 amp. The 10 amp lasted for a while, but eventually blew out. Now as soon as I put in a 10 it blows. There was gauges of some sort and a alarm hacked into the harness that I had to remove. Any ideas on why I keep blowing the fuse?

 

I also have an aftermarket stereo installed, since this seems to be a common problem with people who have aftermarket stereos.

 

Only if wires are hacked to hell. I have never had this issue in any car I have owned where I have installed an aftermarket radio. Sounds like you have too much hacked into that line. If you want to start a cabin fire just keep putting in bigger and bigger fuses until the wires melt.

 

Which line are you talking about? And 10 amp is the biggest I'm going to put in it, thanks for the tip though haha

 

Whatever line is blowing the fuse. I wouldn't even risk a 10amp.

 

pull out your testlight or a multimeter and strart going to town resolder connections heatshrink them and wrap them you have a short somewhere

 

How exactly do I test for a short?
