History, I bought the car about a year ago, 1974 2.0 non-runner.
HEELTOE worked on it, got her all dialed in and running Good. Thanks for that. I havn't driven her much due to some job travel. Sat 5 months, I know, I know, but I wasn't home and the wife think she's ugly and won't sit in it until the new interior gets done. Charge Battery, Start her up, take to car wash, fill tank with Gas. Drive to work and back no problems tops off and loving life. Yesterday, I'm driving home and I hit the brakes, TACH starts swinging back and forth (normally does not work) Red Generator light comes on, and Gas Gauge swings to empty. Odd. Turn on turn signal, TACH swings with flasher, Gen Light on, Gas Gauge swings to empty. This happen today on my way to work again so I think we can rule out intermittant. LOL Gen light now has a constant very dim glow. I don't know squat about electricity, and 30 years of people telling me it's like a water pipe is getting really old. I'm sure I can track down a broken wire, if I know where to start looking, but with all the different areas to inspect, (IMG:style_emoticons/default/confused24.gif) Any pointers on where to start? Thanks for you time. |

Thanks for you time. Alternator belt slipping maybe - if you have a voltmeter check the battery voltage - should be around 12.6 when engine not running, around 13.6 - 14.5 when running. |

Sounds like a ground wire off somewhere. Normally one circuit (like turnsignals) shouldn't affect another circuit (like gas gauge). Some interaction is ok since headlights/turnsignals cause local voltage drops.

The FIRST thing you need to do is check all your fuses. Spin them, remove 'em and wire brush the contacts and the ends of the fuses, maybe even replace 'em, and see what happens. The Cap'n

The 5th fuse from the right (I think) has probably come loose or fallen out. Might be the 4th but I could be wrong?

(IMG:style_emoticons/default/agree.gif) like spoke said "one curcuit shouldn't effect another"... what do they have in common? if they dont share the same ground the faulty curcuit can back feed to get a ground from other sorces when it's own fails. it really sounds weird but 90's g.m. truck's had an issue with thre side marker lights losing grounds. when the turn signals are used BOTH dash turn indicators will flash. this is because it's backfeeding somewhere through another curcuit and getting ground there. take to car wash Yesterday, I'm driving home and I hit the brakes, TACH starts swinging back and forth Turn on turn signal, TACH swings with flasher, Thanks for you time. another possibility: after paint kenny installed the removed tail light bulbs, when the brakes where stepped on the tach died. why? shorted/backfeeding, a 1156 bulb was installed where a 1157 should've been (or visa versa). bulb corrected, no problem. maybe water from the wash got into your rear lights shorting them? those rubber lense seals seem to always be cracked and not sealing |

You kicked a fuse out getting in/out of the car. Ask me how I know (IMG:style_emoticons/default/headbang.gif)

wire brush the contacts Not to state the obvious but you should really disconnect the battery before you wirebrush the contacts ... (IMG:style_emoticons/default/parry.gif) Andy |

That reminds me of the tip I read on here a while back, that a dual filament bulb in the passenger side turn signal will make it so the starter wont stop spinning...electricity, go figure.....
ok..hijack over... (IMG:style_emoticons/default/biggrin.gif) |
