914 electrical issues

Well, the next set of problems. She now fires easily and reuns reasonably well.

Lights work fine. Hazzards work fine. Gen light (it says gen. ) comes on slightly and the battery is getting about 13 volts. I am guessing voltage regulator.

when the turn signals or brakes are used, the gen light glows brightly and neither the signals or brake lights work. Ideas?

SAme issue with wiper motor. Not working and apparent ground problem.

Tach doesn't work either.

Any and all imput grately appreciated.

No tach? Check the fuses. #8 or #9, when popped, will result in no tach and funky alternator warning light behavior.

I had the same problem a couple of years ago. Fuse hadn't blown, just corroded away under the end of the spring clip. Couldn't tell until you actually pulled the fuse from the panel and a little cone of brass fell off the end of the fuse body.

Try pulling all the fuses and cleaning up the contacts a bit. Check your grounds again

The fuses were all fine. There are a few fried wires in the dash and the brake light switch housing is cracked.

The wire that was fried was to the high beam indicator in the speedometer. NOt sure if this is causing some or any of the problems but wahat a strange wire to have fry out.

they can leak at the base of the windshield and water will run down there, or I have seen that anyway. It does not take much water to short you out

I had the same wire fried on my 71. I thought when looking at the schematic that there was no fuse for this wire and it came directly from the battery. Could be mistaken and don't have the schematic in front of me.

I ended up moving the wire to the other side of the fuse where the high beam lamp connects.


I don't think this wire is your issue. You may have a ground loose somewhere. When looking for loose grounds, its good to check battery terminal NEG to chassis; measuring right on the battery post with lights on. If you get more than a couple of millivolts, you have ground issues right to the battery.

Once the battery ground terminal is cleared of any wrong doing, then check wires by measuring from a good chassis ground to all wires including ground wires. Ground wires should be within a few tenths of a volt above chassis ground and positive voltages in the 12V or higher range. You need to do this with an electrical load on like parking lights.

Update: replaced the highbeam wire. It goes to the headlight switch and ofcourse, that post no longer works so either a cob job or new switch is required. Cleaned the contacs for grounds hither and yon and the gen light issue may have gone away but it is still only putting out ~ 12.6 volts w/new voltage regulator. Also, brake light switch repaired but no brake lights and the turn-signal marker deal works (euro one side marker)as do the hazzards but turn signals don't so, if it is possible for a turn signal switch to fail in such a manner then..... but I still believe there is something wierd going on.

Finally progress. With a thorough cleaning of all contacts (including the entire fuse panel)and bulb replacement, we now have turn signals, brake lights and horn!!

Now to figure out the wiper motor and fan. BTW, should the fan switch are be lit?

Also, I really need to do the shifter bushings. The current arrangement is as vague as my old '72 bus, and atleat that one had reverse outside of a plave with a forward gear!

The "climate control" panel will light up with the headlights or parking lights, at least on a 72+ car. The early ones might be a little different--they might only light up when the fan is on--but I'm not sure.
