Electrical problem on RA28

**RA35GT** · 22-07-2009, 10:45 PM

Disconnect the wiring to the regulator (which should disconnect the lamp wire) and then make sure the charge light doesnt come on. This is to make sure the wire itself isn't shorted to chassis somewhere.

If all checks out then you most likely do have a buggered reg.

I disconnected that wire & the charge light went out, it was still illuminated a little bit but its been like that for a while, my regulator must be busted, can you buy a new one or do i need to put an add up...

Thanks again mate... + rep

New ones are available. RA40 units also fit, but you need to get some new crimp ends and change over the plug. KE30 rolla ones also fit.

Any ideas where i would get a new one from and the cost ? i cant find a part number or anything...

Call up Repco or any auto Parts store and tell them what you need. failing that go to an auto eleccy and say, i need a new one of these (take it into him) they may have one on shelf or will be able to get you one by the end of the day.

Good luck.

Ive just asked repco & autobarn, they both said that i need a part number, useless bastards...

27700 (regulator) is the toyota part number if that helps

**KZN130_Surf** · 01-08-2009, 08:05 PM

Yeh that was the part number mate, thanks...

The alternator wiring threads say the alternator should have S, L & IG on the back but mine has F, N & E... Any idea's why ???

Cheers Jimmy

S L and IG is only on the internally regulated alternators.

F N and E is on the externally regulated alternators.

Yeh i thought so...

I went to repco today, had a big arguement with the manager, i have to get a auto electrician to confirm that they sold me the wrong part and they are gonna pay for my new headlights, battery, amp and a new extenal regulator to suit my wrong part... Im not paying for there screw up...

Thanks again
