clock resistor
 

I'm repairing the clock on my 83 300sd, does anyone know the value of the resistor or can give the ring colors mine are burnt.
Thanks Barry

Check this link to see if it has the information you need. Not saying it does but, may be worth a look

Thanks, I can't open the thread from benz. I did some looking online and found someone with the same problem, there burnt resistor read 150 ohm's they and replaced with the same value. My resistor reads 170 ohm's I have 165 ohm resistor that I'll be installing today. Will see if the clock works.

Sorry the link gave you trouble. Tried it and worked for me. Regardless, sounds like you have your solution. Good luck.

Clock repair
 

Here's the step by step that I used...it's a $3.00 repair!

Need two resistors -- Radio Shack part number 272-1028.

I just finished installing 2 new capacitors and resister, bench tested with a 12 V power supply. The gears moved!!!. I'll install it in the car tonight or sat am to see if it will keep time. Dadette I will try the links on my home comp, work won't let them thruogh. 300D I read that link, good info.
Thanks Barry

I would suggest in the future people be careful about testing with 12 volts..
many a dash in automobiles have stuff which works on lower voltage than that...
many with 5 volts in the old days... so you risk burning out something in the process of testing it... which brings up something else... what caused the resistors to burn out in the first place...????? Perhaps some voltage or current reducer is in the circuit and has burned out and should be fixed before reinstalling the new parts.

Leather, Don,t slam me when you have no idea what I do far a living. My car is 12V, it is stamped 12V on the clock and I used one amp on the bench tester to get it to work so I would not fry it.
The resister when bad because the capacitors were old and they dry out. It happens on alot of electronics.

I would have used your name if I was slamming you..
I said people so they would think about this on all the vehicles in their stable..
I said ' many a dash' ... not YOURS is something other than 12 volt...
It is called a " generalization"... and is still a viable warning.

Correct my car is 12V, this form is for mercedes diesels. I don't know of one with 5v to equipment, my 1948 F100 was 6V and my 1968 280 SL was all 12V. Alot of people on this form have had problems like this with their clocks and it has been the capcitors. Look a the links.

Many people on our site are probably not aware that a lot of older cars have a step down regulator for certain dash components like gauges. Five volts if I remember. It usually was in the cluster area.

Testing those gauges with twelve volts would probably do them in. I do not think leatherman was slamming you. I also found those regulators seldom went bad.

You are right in that in most all cases it would not include the clock. The current carrying ability of that regulator was very small. Actually the physical size of the regulator was also very small. Barry.:)

On a lighter note. After watching and thinking about the toyota executives speeches on TV. Their refusal to name the fault that most if not all electronic types suspected. Maybe they just need a new company slogan. Something like Toyota the unstoppable market leader would do.

They seem intent on digging a deeper hole for themselves anyways. The japanese are usually pretty smart. Their performance so far appears to be pretty dumb with this issue.

Barry,
Spot on about Toyota!! Dont park your Benz next to a Toyota, it might catch some of their gremlins!!! :eek:
