Product Description

Tester for relay coils and switch contacts that can be used off the car.

Bad relays fail an automatic test with an indication of good or bad condition. (The red LED will light if the relay is abnormal, but the green LED will light if it is normal)

Power is drawn from the 12 Volt battery on the vehicle. A 12V battery must be used, and the voltage must be between 11V and 15V.

There is a black storage bag included in the package which makes it easy to carry and allows you to test them anywhere you like.

Questions & Answers

Can it be used on any vehicle?

I don't know if this works for the VW

How well does this work with the prone relay on your 2010 Mercedes S550?

If the plug pattern matches the relay, it will work. An inlet picture appears to be in the description of it, showing a 4 and a 5 prong connection. I am not sure if Mercedes has the same design as the BMW, but checking the picture, you should be able to

Are there any reasons why the bigger 5 prone bigger outlets don't function. My relay even acts the same way even after I bought a new one. The red color persists ?

Despite the fact that it's a very good tool, it is not suited to all 4 pin relays

4/5

In order to get the greater pin relay tester, I ordered this item since it stated pin 4 and 5 but when I got it, it is not compatible with the larger pin relay, however, the smaller pin relay works perfectly fine.
