I really need some help with this one, I can't seem to keep my instrument cluster fuse from blowing. I was told to try the EGR wires, plus I've taken the cluster out and it still blows a fuse. On top of that, I have the computer out because I'm changing the EPROM chip, and it still blows. Could I have gotten the wrong relay for either the MAF burn off or the fuel pump? That's the only thing I changed along with taking the intake manifold off and reinstalling it after a port job, but I thought I made sure everything was hooked up. Is there anything I could have screwed up there to make this happen? Does anyone have any suggestions? Thanks

 

Come on guys, nobody has ever heard of this or have any suggestions?

 

easy, just upgrade to a higher amp fuse. Say if you are using a 10 amp fuse, and it keeps on blowing, then use a 20 amp fuse. It won't hurt anything, fuses are designed to blow if high current goes through your system, which is hard to do on a DC electric syste anyway, but a high purge of electricity will be something in the range of 40-50 amps. Later man,

 

I can't even keep a 30 amp fuse in it, been there, got the t-shirt.

 

obviously sounds like a short. Youll hafta check all the wiring on the circuit to find out where the short is. Getting a book with the wiring diagrams should help considerably.

 

Don't install a bigger fuse than it's rated for.
That's how cars catch on fire.
If the fuse holder is rated at 10 amps, that's all the wiring in that circuit can safely handle.

Pull the fuse.
Turn everything off that's in the circuit.
WIth a voltmeter or test light, find which side of the fuse socket is hot.
Insert an ohmmeter probe into the side of the socket that is NOT hot.
Ground the other probe of the ohmmeter.
You'll probably see a low resistance path. Start disconnecting things that are in the circuit untill the resistance goes high.
It''s most likely related to something you messed with recently.
Maybe a pinched wire somewhere or a wire burned aginst an exhaust manifold.

Try disconnecting that relay you mentioned first.

 

 

I went through all of the wires and connectors that led back to the gauge cluster relay and finally figured it out. I disconnected the 2 connections on the air pump and changed the coil and I haven't blown a fuse yet.

 

Ok, I blew another fuse, still tracking it down.
