[diesel_mercedes] 72 220D 4 spd manual

 

hi gang.
well, I've decided I'll not ever get round to fixing the old girl.
the head cracked over a year ago, and well time and money are not on my
side.
there are pics of it on the photo gallery for this group. it's black,
red interior. AC is taken out, but parts are there.
4 spd manual. manual windows. It's dirty from sitting, but a good solid
car *except the engine, which I'd say just needs a new head.*. I have
the old head, but it has 6 cracks according to magnaflux.

Make me an offer, or trade, or cut cards. I'd like it to go to someone
who'll use it, it drove and all very good, all systems working when parked.

It's located in Grass Valley CA.

Henry

[diesel_mercedes] Re: Voltage on 71 220D

 

This goes for all batteries.  The voltage will vary.  After starting for a brief period the voltage may exceed 14 volts.  14.4 would work.  After the alternator makes up for the energy used to start the car stress on the alternator goes down and the voltage regulator puts out around 13.8 or so.  Then as you use power for any 12v need the alternator gives that power or the battery does and the alternator kicks up the voltage to keep the battery charged and supply need amps to devices.  So when you stop your car theoretically you should have a fully charged battery.  This is why you turn off all lights and devices before stopping your engine.  Modern vehicles batteries will not last a long.  They run lights after the car is stopped draining the battery.  So when you start it's in a state of less charge and over time this will ruin the battery quicker.  Just an advantage of the old Mercedes but that said in Europe there are laws mandating parking lights be used.  That wears out the battery too.  Lawrence Rhodes...

That's only in a perfect world. 12.3 could be just fine. Max
