Mechman Alternators

Recommended Posts

I bought 2 320a mechman alts from a mechman dealer about 7 months ago and when i hooked them up the dealer called mechman for me and they recommended I get the dual AVBMii, so that is what I did. It only worked with one alt plugged in at a time. The alts would make a straining noise when the second one was plugged in and voltage would drop to 13v. I contacted mechman and exchanged a few messages with Brian from mechman and he stopped answering me before we figured out a solution to my problem. Two months later i contacted him again and he responded but never answered my questions and when I asked "What can I do to get my alternators running properly?," he never responded. Mechman's customer service is horrible, along with their AVBMii. I would never spend another dime with that company again.

The following is the emails I exchanged with brian@mechman after a phone conversation and he asked for pictures of my setup and he would call me back. (he never did)

What is the year make and model of the truck? Is the alternator controller connected to the vehicle harness or are the alternator stand alone ?

So any ideas on this issue? I read somewhere on a forum that the avbm isn't meant to control more than one alternator because its still only going off the cars field which only has enough output for one alternator. Does this sound correct? I plan on adding a 3rd alternator. What can i do to make them run properly?

Not true. I have a client in NC with the AVBM2 on 5 alternators. Also depending on the alternators used and if the AVBM is installed correctly or not.

I'm sorry that you are upset. I checked all of our e-mail accounts thoroughly looking for the pictures that you sent, and did not see them anywhere. You mentioned that you posted some pictures in the thread, but they are not showing up either. Maybe whatever you are using to send pictures is not working properly?

In any case, we would be happy to sort out the issue for you. You can always just give us a call toll free, or you can just send us the AVBM II for warranty inspection. If there is anything wrong with it, we will of course replace it under warranty.

I dont think there is anything wrong with the AVBM, I just think it is not compatible with my car/alternator setup, which is upsetting because that is what I was told to buy. And I'd rather not spend even more money to ship back and forth for no reason. I just want my alternators to work properly, even if that means tossing the AVBM out of the equation.
