'93 LX 5.0 electrical question...

dwight, don't do it. You know that. Find the real cause and correct it. Check all the stuff under the dash - it could be as simple as a wire hanging down touching the pedal when you push it in...

If your car has cruise you also have the clutch operated cruise disengage switch. Also check for burnt out bulbs ( possibly grounded) in your stop/turn/hazard circuit as it is tied into the cruise circuit too ( the 15 Amp fused circuit you mentioned). StuK

I suppose I'll start with the starter/clutch interlock switch... If that's the culprit, I won't have to start pulling the dash apart. Can you imagine the damage I could do?

?? Brake pedal, yes, but clutch? I remember having the cruise control on (while in 5th gear), and forgetting about it. When I pushed in the clutch to downshift, I revved the hell out of the engine... A tap on the brake pedal cuts out the cruise control.

Sir! There are no burned out bulbs on the Frog! What am I, trailer trash?

There are several 15-amp fuses (light blue). The one I'm talking about is #18 on your menu, and is supposed to control: . safety belt chime (check) . warning lights (check) . fuel injection circuits (I'd swear these were working properly) . tachometer (check - no tach) . idle tracking air control (???) . choke restart control (never had a problem restarting...) . cooling fan / compresser clutch control (which are working, else I'd be overheating all over the highways)

The speed control is in fuse #1, which DOES also control brake lights and hazards.

I'll start with the circuit at the clutch pedal and work my way through...

Sounds like fuse #18 blowing. Power distribution for that circuit includes:

1) instrument cluster 2) air bag diagnostic module 3) warning chime module 4) low oil warning relay 5) low coolant switch

Component locations behind the dash are:

Low oil warning relay at L/H side of steering column brace. Warning chime at R/H side of radio. Air bag diag module at lower center. I wouldn't mess with this. Instrument cluster is self explanitory.

The one component under the hood would be the low coolant switch located in the coolant reservoir.

They all use a *red w/yellow stripe* wire for power, so keep a watch for that when under the dash. One of the power distribution wires may be getting pinched by the clutch lever mechanism causing a power to ground short. Just a little more mental ammunition before you attack the under dash black hole...

Good Luck

Un-plug the clutch safety switch.

Thanks, Mike. Yes, it's #18, and the clutch pedal seems to be the place to start. Didn't know about the low coolant sensor, which might be another likely prospect...
