ALTERNATOR PROBLEMS - CAN YOU HELP?

Has anyone had loose wiring connections to the alternator which come and go - causing battery to discharge and not charge on odd occassions?
If so - how did you fix it?

Mate had a similar problem, turned out to be mud and other boghole crud working its way into the connectors and alternator.

He solved the problem by using a pressure washer to "blast" out all the crud in and around the alternator, as well as disconnecting the wiring plugs and giving them a good clean and spray with WD 40. Works fine now.

His routine now after going anywhere near mud and crud is to get the pressure washer onto the engine and clean everything.

Rudu.
Another cause of this effect is worn or sticky brushes, if the vehicle has done more than 100k it may pay to fit new brushes as a precaution.

Rudu,

I had a similar problem with my HZJ75 Cruiser with the 1HZ motor. I found it to be a faulty wire coming from the plug at the back of the alternator. I only found the fault byhaving the key turned to ignition (no ligts on the dash would come up) and then have a mate wigggle the wiring and plug. As he was mucking around the dash warning lights all started working. Couldn't pin point the exact problem but found that having the wiring loom zip tied in a particular spot it would work OK. Good luck mate.

Cheers,
Hughesy
