Hey all -

73 1.7L FI in a 1971 tub, installed by McMark.

While driving today - I depressed the brake pedal and had the tach, gas go to zero, and the red ALT light light up. Release brake, gas / tach return to normal. Depressing the brake pedal provides NO BRAKE LIGHTS, so that is bad.

Turning on headlamps, operation normal.
Turning on turn signals - tach and gas drop to zero, no turn signals.
No Hazards - but that has been going on for some time.

Prior to this - turning on the turn signals lit up the big red light as the switch flickered, but it also did produce turn signals. Not any more.

When going over bumps - red ALT light flickers, when low RPM red light begins to glow, goes dark with higher RPMs.

Also - when driving today on the freeway after 45mins at high speed, developed a little stutter, not bad, almost un-noticable, not all the time. possibly not related - dunno. (IMG:style_emoticons/default/confused24.gif)

ugh, I hate the elec shit. (IMG:style_emoticons/default/hissyfit.gif)

where to start oh great and wise brain trust.....?????

thanks in advance....

before i get into chasing ghosts I like to do a system clean up. this kills many common problems like voltage drop when pressing teh brake pedal

clean teh chassis ground above teh fuse panel

clean the fuses with a scotch brite pad. only rub in one direction so you dont rip the metal tab off

clean fuse panel fuse holding tabs

clean chassis ground in engine compartment next to relay board

clean relay board contacts and things that connect to it

clean chassis ground strap and attachment points on transaxle and under trunk floor

after 40 years , they all need this.
