[Pman1961]

Got back to the car this evening. Took battery to have tested Sunday and it was fine. Gave the battery a full charge before putting back in the car. While the engine is running the ammeter shows positive even with fans and lights on. Honk the horn with these devices on and the ammeter will drop in the negative zone. Crazy thing the fans do not drop the idle all the time but does the majority of the time. Checked initial timing at 1100rpm and it was at 18degrees with total set at 34. Let the fans drop the idle or just lowered the idle myself to 800rpm and the initial timing fell to 10degrees advanced. Tried lowering the idle a little more and it still seems to stay around 10 degrees advance. Sounds to me that the car is idling in advance as one has suggested and when the fans kick on the timing retards and drops the idle. Does the msd dizzy need to be re-curved or what suggestion does anyone have?
