Would just like to emphasize what was mentioned in a previous post regarding using a test light. They are the best tool for troubleshooting a lot of these lighting issues. A digital voltmeter is a good tool, but I have found instances where the voltage was proper with the DMM, but the failure showed with the test light. This is because the test light will draw a significant amount of current to operate the light. Corrosion or a single wire strand could still indicate the proper voltage due to the DMM not supplying much of a load to the circuit being tested.

Thanks Rich, I have to agreed with you.

I found something better than a test light and volt meter for checking things on the car and motorhome. It is the Power Probe III

Tools for the Automotive Technician and I have a 40ft extension so I can check any thing inside and out of the motorhome, trailer and car. It will test for power, grounds; you can test lights, electric motors, relays etc. Great tool, It was not cheap about 150 but worth the investment for the DIY mechanic.

The following is a quote from the web site and I have done most of the tests myself and I am still learning more about the Power Probe.

“With the press of a switch you'll have an instant hot lead or ground lead. Use the hot lead and ground lead simultaneously to activate components right in your hand. Instantly check components for continuity as well as identify positive, negative and open circuits without re-polarizing hook-up clips. Locate shorts without wasting fuses. The 20ft lead will allow you to test bumper to bumper without jumper leads.

Audio tone indicates positive with a high pitched tone and negative by a low pitched tone. The audio feature can be disabled when testing relays! The Power Probe III has 2 cool white LED’S that flood the work area with bright light. The housing is sleek and feels great in your hand.”

Dave Fernandez,

After looking at the specs for the Power Probe III, it sounds extremely interesting. Also, I found a new Power Probe III (PP319FTC) for $99.78 on Amazon. However, it appears to come with only a 20 ft lead set. But, the remark says the 20 ft lead is extendable to 40 ft. How did you get the 40 ft extension out of this arrangement?

Dave, I just saw that tool advertised in the last two weeks. I wondered how it works. You have confirmed what I had thought.

Thanks

Dale:

The video for the tools shows the 20' extension is included in the kit. It looks like a great tool.

My Power Probe III came with a 20ft extension for a total 40ft.

You can also purchase a 20ft extension from the manufacture Part Page 2 Part # PN3049 - Extension cable for the PP3 (20 feet) with heavy-duty keyed connectors.

I pack it and take with me to Indio and Desert Rat Rallies.

Dave,
Looks like one of those tools I just can't be without.
Thanks

Here is a link to the manual for the PP3 http://www.powerprobe.com/powerprobe/literature_files/PP3_English.pdf

I definitely am going to get one. This would have been great diagnosing my HWH 625 Panel.
