1993 240 Vlovo Amp Draw Running Battery Down?

Hello all

First, thanks for all the aid everywhere. Long story here and then here's the skinny.

Machine: 1990 240 DL Wagon
Issues: Sudden bombardment drain

Ditched my 94' 850 later some caput gasket bug + picked up a 1990 DL for crazy cheap. Simply I've had electrical gremlins ever since. Showtime issue: quick drain with lights dimming + blinkers causing car to dice suddenly when stopped. Resolution: replace voltage regulator. Seemed OK. 2d event: Weeks went by, but suddenly the same bug began happening again. Resolution: took out battery + alternator. Bad battery, but good alternator + bad belt tension. Replaced bombardment + belt. Third effect: weeks went past over again. No problems so suddenly on rolling windows downward I began losing ability one time once more, but not equally bad as before. Left over night + she barely cranked back upwards, only got into a garage to exercise some wire tracing. This is where I am.

Seems fuse circuit number 8 which controls power locks, clock, interior lamps is the culprit. I disengaged information technology, charged it up + this forenoon it started, merely very slowly.

Now I'm stuck. Not certain, but there seems to be a parasitic bombardment drain, but I've disengaged the wire where there seems to be a problem, but getting low power when idle + slight needle jump on the speedometer when idle.

Any suggestions?

Fuse viii covers cardinal locking, interior and glove compartment lights, baggage and engine
compartment lights, radio, ability antenna and clock. Have you checked that the engine compartment light goes out when the lid is closed? Information technology is a mutual mistake on the older cars.

I did check it. Did find though that the wires running to the trunk hatch are frayed. Though I don't open it much I wonder if it's enough to cause a short.

That is a common fault on the tailgate of the 240. Usually it results in total failure of the rear lights when the wires part visitor.

To aid repair these wires IPD, one of our sponsors at the peak of the forum, do a harness repair kit.

Yea doesn't seem to be coming from the tailgate. I'll probably option up that harness regardless. Stranger withal, the speedometer needle merely jumps when the car rolls without me pushing the gas. Gonna try a total recharge of the battery.

After charging the battery fully information technology reads 13.5v. After driving it to work it drained to 12.6 pointing to something with the alternator or chugalug tension I guess. Since it was replaced fairly recently I'g going to double bank check the tension + hopefully that is it.

Have you checked the charge coming from the alternator? A good one should give a reading between 13.eight to 14.two at the battery terminals.

The belt tension should be checked at the mid-bespeak of the longest run on the belt. Using thumb pressure level y'all should be able to deflect the belt by 1/four" - 1/2".

Also, you want to cheque the difference in voltage between +GEN and +BAT. If it is more than 0.3volt, then you should be looking at a poor connectedness. Even a adept alt may not be able to charge the battery well with a drop similar that.

Is in that location a handy version of the alternator diagram anywhere? The voltage on the alternator is consistent with the battery and it doesn't seem to jump when revving the engine. Trying to figure out another fashion to examination the alternator.

Currently voltage on the battery and the alternator read 12.3. Warning bulb does not light up. Wonder if there could exist a connection result there? I'm stumped.

Information technology was .22

No idea.
