I had Mausberry 2A car ingnition switch and today it gone up in smoke.

I test fitted my CarPC in my car, and tried everything with working engine. And then .... smoke...

Mausberry transistor that switches power on and off has gone up in smoke. I dont know why, but I suspect too high voltage (with car running it is around 14V).

Now I am afraid that I can not show this final project in my school.. :evil: :evil: :evil:

I also emailed them.

Do you think this is a hardware issue or my wiring issue?

I think I wired it all correctly, because it worked before with car engine off. But when I tried it with engine running, it was ok for a couple of seconds and then smoke... :( :( :(

I could not find any datasheet for this component 330P that has gone, does somebody know what that is?
I think that must be some sort of transistor. Because now Mausbery switch wont cut power after Raspberry Pi shuts down.

its not your fault , I wired my 2nd switch the same way I did the first one and now it works.
Also the fact that mausberry sent a replacement without any questions lets me know they know about this and it has happened before

I have to thank to Mausberry.
They responded very quickly and was sorry for my problem and they send me a new switch in 3days. Today I received it and it is only 6 days (From USA to Slovenia).
I am very pleased with their service and customer support.

Now I have my CarPC working again.

Good luck! I am thinking that it probably won't last long. I was going to try to find better mosfets for the switch and solder them in myself, but I am having a hard time finding substitutions based on the numbers on the devices.
