Many, many times OP's state they dont have a meter to check voltage or continuity as suggested by those who respond.

I guess the thought is a 'meter' is a very expensive critter.

THEY ARE NOT !

This meter from Harbor Freight is perfect for us.
Only requires a 9 volt battery which can last 2+ years with frequent use.

I grant the version that comes in a fairly soft rubber case doesnt break as often but at this price there is no need for ANY DIY'er to not have a meter.

Whether you use HF or not is up to you. If you work on your MB, get one or at this price 2.

Yes, with only this caution!

Just be careful with testing electronic devices. Doesn't list impedance value.

I have one of these. When they go on sale, they go for less than a decent 9 volt battery...

It's always a much wiser investment to get a good quality DMM, especially since many uses require a frequency %. Keep this in mind. I personally have that meter though as a backup. I throw it in the trunk and leave it there for emergency's.

Clearly this is needed for a proper diagnosis:

Especially on those old 617/616 diesels.

I use a Fluke 335. I find the cheap meters are not as accurate and the leads to be pathetic.
Not for the shadetree as Fluke is cost prohibitive but I use mine weekly and cheap stuff just seems to fail when you need it most.

I also have a Fluke 335 but its not a DMM, my Fluke 335 is a clamp on inductive ammeter probe?

In addition to Amperes the 335 also measures Ohms, AC Volts, and DC Volts. Ohm function tests diodes and temperature. Auto-ranges so no need to select... although it cannot test a junction transistor it doesn't get much more D'M'M than that IMO! ;-)
