Phew! Thanks for letting us know, and thanks to you both for jumping right on it before a nice car bit the dust! Dick Dick Benjamin -----Original Message----- From: mailing-list-owner@xxxxxxxxxxxxxxxx [mailto:mailing-list-owner@xxxxxxxxxxxxxxxx] On Behalf Of Kenyon Wills Sent: Sunday, August 05, 2007 12:22 PM To: mailing-list@xxxxxxxxxxxxxxxx Subject: Re: IML: '72 Dipping Ammeter - resolved Ken Lang came over this AM and after extensive groping UNDER the dash to try to put hands on the clicking relay/circuit breaker, we figured out that the problem was bolted to the firewall. The windsheild-wiper motor was the culprit. Process taken was to run the car, heat up the offending item, turn car off with ignition (and current) still on, and start listening/probing for the item that was clicking. After not finding it, Ken noticed that the wiper switch was at 1 instead of 0, and toggled it. No response from the wipers, but a big jump on the needle! There you go!!! That is now disconnected and the car runs correctly.
