NEED HELP WITH ELECTRICAL PROBLEM

[Travis_R]

TRACTOR IS FIXED!!

Thanks for the replies support once again.

The problem WAS the AMP METER. All the lights, flashers, and charging system are working properly. Everything is back to normal.

Just the GAUGE by itself (without tax or shipping) was $30.10. TAX was $2.55 and FREIGHT was $7.50.

TOTAL cost came out to be $40.15 delivered to my door, which wasn't bad at all.

For future reference:

**********1997 MAHINDRA 485 DI AMP METER GAUGE PART # AS OF 1/11/07 IS MAHINDRA PART #5550919R91***********

I am glad that fixed your problem. I do however have some reservations that it has fixed the entire problem. Part of the nature of having a short is that they are very transient. If you have a bare spot in a wire that touched the frame or any bare metal then vibrations might cause it to touch again and blow the fuse again . Let us know if that happens. If It dont then congratulations on your fix.

I've also been thinking about that. First post said blown main fuse; replaced; didn't fix pblm. Later discovered bad Ammeter. Still later, not sure if original fuse was really blown.

If that main fuse did blow, then POSSIBLY a transient dead short with the fuse sustaining an arc long enough to take out the ammeter - or vice-versa. Then could happen again. However, if that original fuse was really OK, then PROBABLY defective Ammeter. But then during my 7-8 years in the '50s/'60s as an electronics tech I saw plenty of weird stuff that didn't seem logical. Time will be the final arbiter.

Fredex I agree it is hard to tell and shorts are extremely hard to find. I have been working in electronics since 1971 and every time I see a short issue I groan. As I said in an earlier post my fathers pickup when I was younger had a short in the tail lights you could replace the fuse and then you could drive a day or a week or a month or 5 minutes before it would blow again. I checked every wire I could see replaced all the tail light bulbs etc nothing I did found it until I finally got tired of dealing with it. I replaced fuse with a piece of 12 gauge wire and waited finally one day I got smoke coming from the fuseholder and then it was pretty easy to see what happened the wire burnt from the fuse holder down to under the cab. When I replaced the wire I saw that what apparently had been a nick in the wire, when you hit a bump the nick would hit a seam in the sheet metal and short out. I would not recommend that troubleshooting method to anyone You can wind up with big problems from it but I had been working on his truck for 6 months. I would keep it for a week and drive it then give it back to him and the next day he would have a blown fuse. I replaced the wire that burned up and he did not have any more problems.
