Member Jonathan Kay Posted March 4, 2020 Member Share Posted March 4, 2020 Is the bonus problem fixed, so that we can now work through the original issue with the warning light?There's another Member with problems on a 310.ThanksJonathan Link to comment Share on other sites More sharing options...
AMBO Posted March 5, 2020 Author Share Posted March 5, 2020 Not yet Jonathan! Will update as soon as possible... Link to comment Share on other sites More sharing options...
AMBO Posted March 28, 2020 Author Share Posted March 28, 2020 Right, my ECU is repaired and the car runs again, so I'll update this thread tomorrow regarding the alternator wiring... Link to comment Share on other sites More sharing options...
AMBO Posted March 29, 2020 Author Share Posted March 29, 2020 The conclusion is that I connected the wire that originated from Brown/Yellow to the L and the White wire to the IG and we now have a working ignition light, which goes out with the engine running and the battery is charging well, but not too well!The Green/Blue I've left disconnected as before as it all works without. This leaves the S or D as per Brise diagrams not used.Thank you again for all your help chaps...and hope we all get to enjoy some summer driving, even though it looks like it could be a good few weeks away yet...Best Wishes, Nick Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted March 29, 2020 Member Share Posted March 29, 2020 Thanks for the information. I'll try and work through that.... and the battery is charging well, but not too well!What's the voltage at 3,000 rpm now?Jonathan Link to comment Share on other sites More sharing options...
bjw Posted March 29, 2020 Share Posted March 29, 2020 It doesn't sound as though you have tried connecting the sense 'S' terminal to battery +ve as suggested?If the alternator is designed to use the sense input it may well default to a nominal output if left disconnected.From a Delco-Remy document regarding such alternators:-Connection of the Remote Sense terminal is best for optimum performance; however, the alternator will function without Remote Sense connected.

AMBO Posted March 29, 2020 Author Share Posted March 29, 2020 At 15-1700 revs it was 14.3 Volts... Link to comment Share on other sites More sharing options...
AMBO Posted March 29, 2020 Author Share Posted March 29, 2020 As it seemed to be working ok, I wasn't feeling brave enough! If designed as suggested, presumably the alternator will charge as required depending on battery voltage, if I connect S to +ve? Link to comment Share on other sites More sharing options...
bjw Posted March 30, 2020 Share Posted March 30, 2020 14.3 volts doesn't sound too bad if that's measured at the battery rather than at the alternator.The sense wire is designed to compensate for the voltage drop in the wiring between the alternator and the battery when there's a high load - e.g. the battery is taking a large charge current or the headlights, radiator fan etc. are on.If you run the engine with as much electrical load as possible, and connect a sense wire and the voltage rises then you'll know whether it's worth fitting permanently or not.Cheers Link to comment Share on other sites More sharing options...
AMBO Posted March 30, 2020 Author Share Posted March 30, 2020 14.3 volts was measured at the battery. I will try what you've suggested...Really appreciate your help and explanation! Best Wishes, Nick Link to comment Share on other sites More sharing options...
AMBO Posted March 31, 2020 Author Share Posted March 31, 2020 Tried a sense wire from the S or D connection to the battery +ve, but it didn't make any difference...Engine running but no electrical load gives 14.3 V at the battery whilst idling. Add mainbeam, hazards and heated screen etc and battery V dropped to 13.3 to 13.6 V, again at idle. With revs up to about 2000, the battery shows 14.4V, with or without the sense wire connected...I'm a happy boy now!Cheers Nick Link to comment Share on other sites More sharing options...
