More electronics fail

This is incorrect.

The Only way to test a battery is under a load. A multimeter will not and can not load a battery for testing.

Turn a few heavy loads on and you can do a decent test with a voltmeter.

Rear defogger, all the lights, fan motor on high, etc.

You can put a 40 or 50 amp load on the battery.

Much better than just measuring the voltage.

This is a better test, but nothing like the load a starter motor will put on it, or a load tester.

Alright now I'm pissed!!! Car is supposed to be under warranty and they charged us $386.20.

$87.50 tow
$337 for " Performing software update in motor electronic control module" Short test codes 1108,0190,0217, 0551, 1916 etc all relating to throttle actuator blah blah blah.

PS buy American, old preferably.

I'll get tow money back from my insurance but gotta fight merc for the rest. My wife can write the letters I did my part. Paid. Would not have paid had I'd been there.

Dude you been screwed. They Merc should cover the tow and all. It is harder to undue after its paid too. Possesion is 9/10th ...

LOL you just learned European cars are shit with electrical problems??

Everyone know to avoid them like the plague. BMW, Mercedes, VW, etc...

They are an electrical nightmare.

Top Gear convertibles part 1
part 2

Saw this repeated over the weekend and though of you 🙁
(skip to the end of part 2 if you want)

I can't believe they charged you $386.20

If it will crank, then you measure the voltage while cranking it.

If it won't, you gotta use whatever other big load you've got. :biggrin:

Ill take solid state sensors and a data log showing me exactly where the problem is over manually checking over miles of vacuum hoses, diaphragms, and sticky worn out crusty mechanical actuators and best guess divide and conquer troubleshooting any day.

Anyone who dislikes current EFI systems because the are too "complex" needs to work on a few cars from the 70s/80s.

pumping out the data in ASCII and plain text like "PRIMARY HEATED O2 SENSOR FAILURE" over a nice old RS232 serial port would make a lot of people happy

This is why I love my Saturn S-series so much.
They are so simple and inexpensive.. It is just a good feeling working on one.

Hard to measure and crank by yourself.

You mean I gotta hook my wife up to it?
