Hi,

 

I need to get a digital(?) multimeter to help me troubleshoot simple electrical problems. Anybody have any suggestions?

I have always liked Fluke multimeters.

I have this Fluke.

You can find multimeters for $20-$40 that will meet most simple needs.

Amazon has dozens of selections at all different price points. I use Amazon's online catalogue to do research and then try to source from a local vendor or a mom and pop shop. Here is a link to the one they recommend for $12.99 - https://www.amazon.c...2xpY2s9dHJ1ZQ==. Best of luck!

A general purpose, good quality  DVM can be purchased new for between $20 and $40.   The precision ones with more features will likely be over $100.   

 

The secret and key to a DVM is to learn how to correctly use it and understand what it is telling you.   The last 6 words in that sentence  "understand what it is telling you"  is the most important part of using a DVM.  

 

If you will learn OHMS LAW, you'll have a much better understanding.  

 

I = E/R   E = I x R   R = E/I and P = I x E.    where as:   I = current in amps, E = volts,  and R = resistance in ohms. 

 

There are other formulas, which you should be able to derive those from high school algebra class.   Remember those stupid formulas you swore you'd never use in life?

Since much of our trailer electrical systems are 12V DC, one thing to consider is spending a bit extra for a clamp on meter that will measure DC current.  While clamp on amp meters for AC are numerous, you need to look a little harder to find one that works with DC.  Very useful since you don't need to disconnect wires to put the meter in series to measure current.  Mine is a discontinued  Amprobe AC/DC 3000, but there are plenty of others.  While I prefer major brands such as Amprobe & Fluke, an inexpensive AC/DC clamp on meter that will do for most is under $50.00 at Amazon.
