^So just getting some wires with leads and connecting it to the battery should be okay? I was thinking about doing that, but didn't want to fry the servo. I'll give it a shot.

Yes BUT !
 

You cannot just connect voltage willy-nilly and hope you get it right :eek:

It's very important to follow the correct procedure .

Otherwise you'll damage the servo .

Also that servo operates off about 5-6 volts, a full 12V might damage it.

Use alligator clips crimped onto some wire.....

Servo Motor Voltage
 

Yes , the amplifier reduces the voltage but no , 12 VDC directly from your battery won't hurt it.

Obviously , once it stops moving , you don't leave the wires connected and have a beer......

Found another amp in my garage and tested it, it actually varied with the change in the thumbwheel. Here is what I got:

Also I connected power from the battery to the servo and got no response.

OK so it appears that your amp and CCU are working properly, but your servo is not.

Oh joy. Well I guess there is only one thing left to do then.

Paging Jimmy...

Bypass, Bypass, Bypass.

But but but...I'm so close!!!

I might have to for a quick fix.

This is a Mercedes-Benz, not a old Chevy, lets do this the right way.

I've seen just as many bypasses as I have functional evil servos with the ACII system. Its a Chrysler designed farce that does not belong under the hood in the first place, IMO.

That was a newly rebuilt servo that I bought, and paid a bunch of money for it. Maybe you can contact them to see if they'll send another?

...or in 30 minutes you can put in a nifty little manual valve that only the biggest Mercedes nuts will notice, most of them will completely understand why.

By installing a bypass valve you loose the systems original function.

I had my servo replaced about 6-7 years ago with a alum body unit, it has worked great ever since. When all is well its a good functioning system.

I don't mind bypassing the system temporarily, but I do want the car to have it's original functionality. If the servo system in it right now fails again, I will go with a digital servo. Basically I want Norm to be operational like it was in 1980.

I'm sort of slowly "rebuilding" Norm, and would like to sort out everything like it should be. If all that is left is for me to try a different servo and it works, then awesome that's what I'll do.

Jimmy is sending me his to test out. If that fails then I will rig up a bypass until I am able to have my servo rebuilt or until I can purchase a digital servo.

ATTA BOY !
 

That's the right attitude .

Never give up , never say die .

:D

By some miracle I got the servo rebuilder to send another one, only requiring a core deposit. Considering I ordered the part 18 months ago that's pretty impressive on their part. I left Colin a lengthy message.

Anything for good ol' Norm. :thumbsup2:
