Main ignition fuse keeps blowing.. HELP!

I have a 09 Murano LE, 2 weeks ago I had the battey and a battery terminal replaced as it was the original and had died after sitting for 3 days or more. A few days later I went to start it and nothing .. Push the button and other than a relay or two clicking under the dash nothing. I had it towed to the dealer. After two days, I am told by the dealer, that I popped the main ignition fuse prob due to jumpstarting. 22 hours after picking it up, it happened again... After 3 days of "diagnosis" they bone my Viper remote start. After unhooking it they think they have solved the issue. 36 hours later it happens again now they have had my car 5 days they still haven't figured out what is causing the issue. Any thoughts?

That can be tough. I agree with them that disconnecting any aftermarket stuff connected to the faulty system is a good idea - the quality of the installation work on those varies drastically.

I think I'd start by checking ground connections between battery and chassis, and between engine and chassis. Most people tend to check the + side and forget that the ground has to be good.

If the battery is being drained while sitting, that's a different problem than if it's not being drained but still not making contact.

Finally got an answer ... When the battery was changed apparently the shop dropped a wrench which slipped under the air box. As it jiggled around when driven it would short on the wires leading to the starter. Hopefully the shorting didn't cause any other issues .. Fingers crossed!

Oh, s%@#!

If it's not tough enough to guess electrical gremlins, they have to throw this little mistake into the mix.

Chances are that there's no damage to the wiring. Murphy's Law in action.

Ask the shop to pay you back for your expenses.
