Alternator removal and servicing
Alternator failure message
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".
On some cars, this message may indicate a proble with, eg, the battery being due for replacement, and/or the battery connections being loose. On a Soarer, this message generally means what it says; there's insufficient charge coming from the alternator.
Confirm whether the alternator is faulty
As removal of the alternator is time consuming, please confirm whether the alternator is faulty before removing it. This can be done by, eg:
- measuring the battery voltage (which would be around 12v with a charged battery, but dropping slowly as it is not being charged and the full load of the vehicle electrical is borne by the battery
- removing the positive cable from the battery while running. If the alternator is generating power, the vehicle will keep running and the voltage generated would be in the order of 14v. With a faulty generator, the voltage and/or current would be less, and often zero. In that case, the engine would stop.
Alternator removal
To remove the alternator:
- Find the alternator!
- Remove the cover from the Cruise Control
- Remove the air box (including the Air Flow Meter and "concertina pipe" by loosening one hose tie and removing 3 x bolt)
- Remove the vacuum hose that is in the way
- Remove the second vacuum hose
- Remove the 3 x bolts holding the side of the power steering reservoir (taking care not to lose the bushes that are now loose in the bolt-holes)
- Remove the bracket holding the hydraulic line
- Remove the bracket holding the electrical connector from under the air box
- Remove the front right mounting bolt from the alternator
- Remove the serpentine belt
- Remove the front left mounting bolt from the alternator
- Remove the rear alternator mounting bracket
- Remove the earth connection nut and cable
- Remove the electrical cable connector cover, then un clip and remove the cable
- Remove the alternator by turning his way and lifting it out

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'

Ok, that number was wrong, it was the part for the 31. I had to send it back.
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.
