OOPS alternator woes.

<< < (3/3)

Mr Bump:
Possibly, scuse my mechanical ignorance but is the servo the circular black thing?

hobbit:
Usually has a fluid resevoir on the top of it, and a hose from it to the unit you have there

veeeight:

--- Quote from: "NewBloke" ---Had a play in the mud on Salisbury Plain this afternoon but finished the journey home on a flat bed.

looks like the alternator is FUBAR

I'll apply the normal fixing teqnique of jetwash and WD40 tomorrow and check for any obvious loose wires.

Andy, if your alternator has a seperate brush/regulator pack on the back held on with 3 x 8mm head bolts, then that is probably your problem, if you take that of very carefully then you will more than likely find that the brushes are all gummed up with mud, (happens alot to mine as I cant keep out of the muddy ponds :lol: )
If you spray the brushes with WD40 and push them in and let them spring out, keep doing this untill they are nice and free then re-fit the pack (even more carefully than you took it off as its easy to snap the carbon brushes off :roll: ) and that should solve the problem.
Alternativly you can buy the brush pack/ rectifier from any good motor factors and replace the whole thing, alot cheaper than an alternator, I keep a spare one in the shed.
I got to do mine after Slindon on Sunday, Mine went after a couple of hours and ended up running both electrical systems off the one alternator. :lol:
