Tom, I noticed after I emailed you last night that there was another post in which you said that the car wouldn't start when you had the regulator plug apart - I presume it would crank over but there wasn't any power at the coil. Interesting, sounds like they feed the ignition via the regulator somehow through the ammeter, so the 240K ammeter must be an active type (as in if it fries you stop and scratch head) and not a passive sensing type like in H*ndas & Toy dashes. When you had the 12v light running to the S terminal on the alternator and the ammeter was showing charge @ +30A, did the alternator appear to be actually charging. This is the sort of thing that auto sparks do all the time, and unless anything gets hot or sparks fly, there very rarely is any damage likely to be done. I wouldn't source the S feed from the old external regulator though as that is likely to get things excited and it would need to be ignition activated to work properly.
I'm thinking this may be OK, as you don't have a F(ield) wire connected then the Ex reg shouldn't active anyway but it will provide the ammeter circuitry and it shouldn't affect the IR reg alternator. I'd need to see the schematic diagram to know how they run the ammeter and ignition feed to the coil. I'm pretty much stuck at this point - interesting problem though. regards Terry -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Tom Richardson Sent: Tuesday, 31 December 2002 12:52 AM To: [EMAIL PROTECTED] Subject: Re: Alternator regulators > > >then you probably have only connected the Batt wire and an earth >at the alternator end. > > Correct. >many wires are in the plug.

We did have the 'S' light on 12V briefly and it ammeter showed +30A, but we disconnected this as we weren't sure if it would damage the IR. Are we on the right track - do I need to make myself a charge light circuit to agitate the alt?
