2.3 keeps discharging August 29, 2010, 11:30:28 AM I just replaced the alternator with a new one and my blue top ultima is good, but the thing keeps discharging. I took it back today and it said the low pass reg is bad. What the heck is that? I thought the reg is internal? I have checked the lights and cant find anything left on. Whoever wired in the remote system, must have put a timer in the fan cuz it runs for 2 minutes after shutdown. This problem has just started though. Quote Selected
2.3 keeps discharging Reply #1 – August 29, 2010, 01:37:37 PM Disconnect the negative battery cable and connect a test light between the cable and the negative battery post.If you have everything off and the light is on, you have a drain.Take all the wires off the positive battery cable side of the starter relay. The light should go out.Put the battery cable back on the starter relay. The light should stay out. If not the problem is with the starter relay.Touch each wire one at a time to the starter relay terminal to see which one lights the light.Let us know what you find. Quote Selected

2.3 keeps discharging Reply #5 – August 29, 2010, 03:24:53 PM I am using an 87 EVTM so there may be some differances.The green wire (fuse link) goes to the ignition switch and the fuse box. The alternator, regulator and the rear window defroster.The yellow wire goes to 6 fuse links.Link A: The under the hood light. The EEC keepalive voltageLink B&C: Anti-lock brake relays.Link D: Programmed ride control relays.Link F&J: Integrated Controller Module.The integrated Control Module is a black box under the hood.It has 2 fan control relays, EEC power relay, fuel pump relay and the A/C clutch control inside.Can you unplug the connector on it?

2.3 keeps discharging Reply #6 – August 29, 2010, 03:56:41 PM I think I found it. I went to the ignition switch to see if there was a short and one of the wire had pulled out of the socket and was probably shorting out. I rewired the plug a couple months ago and this particular wire was in a melted mess from the old switch. I think I damaged the locks getting it out. As soon as I hooked it back up the light on the negative lead went out. Thanks for the help...i didnt think about using the light like that!BTW...Do you know which wire on the ignition module controls the TEVES? Both the Brake and ABS are lit up and the brakes are like a rock. I have tried the troubleshooting tree on NATO, but this is odd. If I drive it long enough the lights go out, and I will get one good, full shot of brakes, then the lights immediatly come back on and the brakes go back to rocks. Someone spliced in a remote control system, so I think it may be a short. Quote Selected

The ABS light is turned on by the ABS Electronic Control Module and the brake light is turned on by the brake fluid level sensor.What is the "remote control system" supposed to do? Quote Selected

2.3 keeps discharging Reply #9 – August 29, 2010, 04:59:10 PM The TEVESII is the great big lump of a brake booster with the gallon jug on top.The remote control...basically someone wired in one of those keychain remote starter with remote lock/unlock of the doors and trunk. It is pretty cool, but EVERYTHING is spliced. LOL Quote Selected
