DC_ Posted November 20, 2009 Share Posted November 20, 2009 Recently got a new (ish ) Alternator from a freindly forum member but it turns out to be slightly different to the one that was originally on my 92 RRC 3.9 EFI The original one was i believe the A133 (??) and the one from the forum member is A127. Would i be able to connect existing wires from my loom to this Alt? From memory from the weekend, i've got 4 wires to connect to the Alt. Main live wire to Solenoid (1),Small brown(2) Spade terminal(3) which has a feed from same wire?(4) I reckon i know where the Wire to solenoid goes, and the small brown, and i take it the "W" on the rear of the Alt is for the Rev/tach? I know which wire is for the Rev/Tach but there is another spade terminal coming off of that too, so.............Would this connect into a suppressor? I think that would still leave me with a dangly bit on the Different Alt. Any help would be appreciated Cheers Quote Link to comment Share on other sites More sharing options...
DC_ Posted November 20, 2009 Author Share Posted November 20, 2009 I'll have to go out tomorrow and try it so i don't wanna blow myself up Anyone? Quote Link to comment Share on other sites More sharing options...
Bull Bar Cowboy Posted November 20, 2009 Share Posted November 20, 2009 Yes, you are about right although there should be only 3 wires + maybe a suppressor capacitor, but that is normally bolted to the back of the alternator. The large live output feeds back to the starter solenoid then onto the battery, the W is the tacho feed and the other wire is the ignition or battery light ......... some alternators are marked IND.......some are marked I..... and some are marked L..........

DC_ Posted November 22, 2009 Author Share Posted November 22, 2009 On the Tach wire (not on the Alt) there's another feed from it with a spade connector on it. would this connect to the suppressor? Quote Link to comment Share on other sites More sharing options...
errol209 Posted November 22, 2009 Share Posted November 22, 2009 On the Tach wire (not on the Alt) there's another feed from it with a spade connector on it. would this connect to the suppressor? Probably, to stop the windings transmitting a whine over the tacho line. Quote Link to comment Share on other sites More sharing options...
DC_ Posted November 22, 2009 Author Share Posted November 22, 2009 So it doesn't get connected to anything? Quote Link to comment Share on other sites More sharing options...
errol209 Posted November 23, 2009 Share Posted November 23, 2009 So it doesn't get connected to anything? Well, you could fix the "issue" by buying and fitting the suppressor ... Quote Link to comment Share on other sites More sharing options...
DC_ Posted November 23, 2009 Author Share Posted November 23, 2009 There's 2 Suppressors on the Alt, one is connected into the Alt itself and the other is the one in question about the Spade Connection cominf off of the Tach wire. Quote Link to comment Share on other sites More sharing options...
