EURON8 Posted November 14, 2011 Share Posted November 14, 2011 Van is being pissy again. OK, i will try my best to explain the situation Alternator light on Found voltage reg Found wire that triggers warning light etc. When plugged in and vehicle running, the solenoid does not move. Manually pushing it turns warning light off Supplying 12v from earth to appropriate terminal triggers the solenoid and makes it do what it should Have tested the correct wire from alternator to reg and it has no breaks3 With vehicle running and volt meter from earth to pin on alternator that should supply current the trigger above solenoid gives 1.2ish volts at idle and bit over 2v with some revs. This is a long winded way of asking what voltages should i be seeing? The alternator has 5 wires. The 2 big ones connect to the same terminal and see about 11.8v at idle The other three are in the same 3 pin plug and all are getting some pretty low voltages or none prehapos. This is all leading me to believe a bung alternator. however, This is the same one from the old motor and none of the vans wiring loom has been altered for the conversion. It was working perfectly on the old motor, and worked at first with new motor then didn't, then did now doesn't again.. The only issue is the loom was getting some pressure on it from various hoses which have now been moved. All wires i've tested and my understanding of the circuit and how it works points to no breaks in any of these wires. go! Quote Link to comment Share on other sites More sharing options...
R100 Posted November 14, 2011 Share Posted November 14, 2011 Open up the alternator and check the brushes. That may be the problem Quote Link to comment Share on other sites More sharing options...
phtmbl Posted November 14, 2011 Share Posted November 14, 2011 external regs can cause some fun problems, my one would travel about 50km then stop working untill it was cold and then work fine again. Quote Link to comment Share on other sites More sharing options...
DavidTheCreator Posted November 14, 2011 Share Posted November 14, 2011 the terminals at the alternator,regulator and battery are all clean and tight? Quote Link to comment Share on other sites More sharing options...

slacker.cam Posted November 14, 2011 Share Posted November 14, 2011 Apparently the alternator has been checked and is good. It wouldn't hurt to pull it out and check it yourself though. Unless you have a wiring fault then I'm struggling to see how it can be anything other than a faulty alternator. I take it you tried that other regulator that I gave you?

EURON8 Posted November 14, 2011 Author Share Posted November 14, 2011 that reg u gave me is different. Mine has a secondary contact on one solenoid which the new one lacked. Mine also had some diode thing across some terminals. I tried it anyway. Didnt work. Will pull it out and clean it. Pain in the arse as its square peg round hole kinda deal getting the thing in and out of its little posi. Quote Link to comment Share on other sites More sharing options...
DavidTheCreator Posted November 15, 2011 Share Posted November 15, 2011 sounds like me trying to get the startmotor out of a holden v6 in a hilux. get a sparky to run it up/bench test it Quote Link to comment Share on other sites More sharing options...
shavenYak Posted November 15, 2011 Share Posted November 15, 2011 My Hiace is doing pretty much the same thing - charge light is always on, but alternator is definitely charging. External regulators are a pain in my bleached asshole. Quote Link to comment Share on other sites More sharing options...
R100 Posted November 15, 2011 Share Posted November 15, 2011 Bring your old alternator in to me at work. I can bench test it or swap it for an internally regulated alternator as i have about 20 in stock off various cars. Maybe we can find one that has similar mounting brackets. I also need to point out all this will cost you nothing. Quote Link to comment Share on other sites More sharing options...

Seedy Al Posted November 17, 2011 Share Posted November 17, 2011 Although your alternator maybe charging, but the light is on, doesnt mean its charging at the correct voltage, make sure its not Exceeding 14.4V Quote Link to comment Share on other sites More sharing options...
DavidTheCreator Posted November 18, 2011 Share Posted November 18, 2011 or is charging to low and has dropped a diode Quote Link to comment Share on other sites More sharing options...
