706 Amp Light

Cmore · Apr 20, 2012

I picked up my "new" Class of 65 706 yesterday. Ran great at times but needs new fuel filter and sediment bowl cleaned out good and 93 octane gas. Also the Amp light keeps blinking. What's that all about...not charging or something else?? Thanks, Cmore

Does it have an alternator or generator. If it has a alt, chances are one or more of the diodes inside the alt are bad, letting ac current out with the dc.

It's a 65 model with a generator?? New brushes needed or new voltage regulator maybe?? Cmore

There is no fuel filter in these from the factory, only a sediment bowl.

If yours has a filter cut into the line somewhere, that is probably the problem. People put them in thinking they're doing a stroke and they usually use the wrong type of filter.

IH didn't switch to alternators until the 56 series AFAIK. Use JohnT's generator troubleshooting guide to diagnose the problem. Could be brushes, could be ground, could be regulator...

A 706 only has a screen in the sediment bowl no in line filter So if it has one of them it need to go as you stand a chance of fuel restriction . IF the amp light is ah blinking she is not charging , i am not sure of the S/N break when they went to the alt from the gen. but i am thinking late 66 and 67 . IF it is a gen. then with out looking at your tractor i am guessing that more then likely the gen needs rebuilt IF the wiring is in good shape . The gen. system works ok if you don't get carried away with a bunch of lites . The one 706 that my friend has about drove me and the guy that does my rebuilding of the starters and alt. nuts as it would test good on the bench but on the tractor above half throttle the lite would faintly blink. I thought that i was going to wear out the threads on the nuts and bolts putting it on and taking it off changing regulators testing wires got mad and rewired the harness from the reg to the gen and still had the pesty blink as they finally found the problem in the fields and once they replaced the fields that gen. has been on that tractor now for 12-15 years now.

Check the charging voltage at the battery at 50% throttle. if it is above 14 volts, good. Turn on the lights. If still above or aty 14 volts keep driving it, the regulator is working, it just blinks the light. Jim

Yea they did put alt. on 706's late 66 and 67 706's came with alt. on the C291 and D310's

What we found after many attempts on Eugene's what was tripping the lite was bad field in the gen , and the way Crazy Geroge found this was he got mad and instead of his normal way of testing fields that always showed that the fields were good he hooked the fields to 110 volts and THAT finally showed the problem put new fields in and problem solved.

You Know, I know a few people that look at me like I'm and Idiot when I tell them that a filter will restrict a gravity flow system. I tell them that it's happened to me, I did it and learned from my mistake, they laugh, leave the filter on, cite "crud in the tank" as a reason, and then wonder why the tractor won't get enough fuel when plowing. DUH!

Thanks Tractor Vet...your the Man...it does have a fuel filter...which i will get rid of..and clean out the sediment bowl real good...and fill 'er up with 93 octane gas...well, don't know if I can afford to quite "fill er up"...and I'll have the generator checked out...Cmore
