Hi. I have a Mitsubishi Minicab Bravo van. Someone hooked up the battery backwards.. looking for some answers in the web

Mechanic's Assistant: What is the complete model and serial number of your machine?

Model V-U41V HLNSV 3

Mechanic's Assistant: Are you fixing this yourself? What have you tried so far?

Yes I fix it myself. The internal roof light comes on. The head light comes on. Hazzard blinkers comes on. No dashboard lights or ignition lights comes on.

Mechanic's Assistant: Anything else you want the equipment mechanic to know before I connect you?

No. I need an experienced person to answer me. Multiple things may have burnt.. such as alternator, etc.. So I would need a step by stem guidance.

Usually, when the battery is hooked up backward , it blows the fuses to the main functions, have you used a voltmeter and checked each fuse in the fuse box? Net would be to look for a fusible link, on the battery cable negative side, that would be an extra wire, that completes ground for the functions. A fusible link looks like a fuse that is soldered in a wire. You have to check it with voltmeter or ohmmeter for continuity

Hi Curtis. If the fusiblr link is gone, then headlight power and indoor light power should not be comming. In this case, the headlight, hazzard blinkers and inside room light works. Its ths ignition system that does not get the power. I check the fuses under the dashboard. all are ok.
Need to figure out the first affected component and then work my way upto the alternator. I'm sure the alternator circuit is gone
