new holland IH 248 tractor problems

[sparkyork]

hi all, first post here

my friend has the above tractor and is farming sheep etc, small scale but hoping to grow.

im a electrician by trade and he asked if i could have a look at the electrics for him.

pretty much nothing works, thought i found a feed at the rear lighting but cant decide if we have earth problems or something from the switch side of things playing up. didnt have spare wire to come stright from the battery to verify earth etc.

just wondering if anyone has any clues or wiring diagrams available

cheers

A good place to start would be at the 2 fuse boxes on the cab bulkhead.Under the battery cover on the bonnet. Old type glass fuses... You likely know the score with them and corrosion...

yeah seen them, they dont look to have blown but a tad susseptable, over near the alternator is a green and yellow wire that looks like it came from the alternator but allready has 3 connections under a plug

The green/yellow should go to the blocked air cleaner sensor I think.

Just found this...

The 248 is just an industrial 484/485.
