Isuzu Wizard Mu 1998 Alternator Issues.

Postby Johnfrancis » Wed Jul 12, 2017 6:52 pm

Having issues with alternator not charging the battery.Charging up the battery with battery charger each night. Voltage reading approx 12.3V and then steadily decreasing over day (on dash voltmeter). Rev the engine but no change on multimeter reading when connected to battery (Calcium...needs higher voltage to charge). Tightened up the belt that drives alternator but no change. Just wondering before I buy a reconditioned unit is there a relay that can impact on the alternator charging...I read something about a dead charge relay which is a common fault (http://jasoceania.co.nz/articles/two-mi ... lternators). Thanks for any help.

the charge relay is the brown one inside the fuse box (might be blue) Normally they only die if the stator coil fails in the alternator so even if this relay is faulty the alternator is suspect. Auto sparky can test it easily and cheaply
Sanding your knuckles before starting work can help. That way you cant skin them
