Alternator

Alternator failure message

Alternator not charging

When the ignition is on, but the engines not yet started, the display will display (in English) "CHARGE" - this is normal. However, when the alternator is not charging, a message will be displayed in Japanese, which, when translated, means "Alternator not charging".

Confirm whether the alternator is bad, eg by measuring the battery voltage with the vehicle running and/or removing the positive cable from the battery while running.

Posted: Mon Aug 19, 2013 8:08 pm Post subject: I feel a bit of knob writing what I did - I only had to do some proper investigations.. and I found the diode rectifier was faulty. Getting a new one proved tricky because they are not available anymore (for the UZZ32). However a 90-92 alternator for a MR2 happens to have near identical parts from its Nippon Denso alternator. Whilst the alternator itself isn't a fit, the diode rectifier, the brushes and the regulator are. I canibalised a MR2 alternator and rebuilt my one. Result! Works fine now. Done 1200 miles and all well. _________________ Jake Purches 'The Prof'

I have sourced the right parts for the 32 alternator from someone here.

The parts are as follow:

Brush holder 39-8203 Regulator 15-8351 (same as for the 31). Rectifier Transpo CN-INR736-0073 (this is 32 specific with right angle rear external connection, not straight out as with the 31, which has the big wire on the side).

My alternator is now up and running perfectly.

Note: When you undo your lower engine mounts make sure you undo the transmission mount too, so as to allow the motor to tilt without straining your mounts.
