View Full Version : Strange Electronic Problem...HELP!

2006.08.12, 12:25 PM
OK, well basically my MZM has no motor when the power is on( no throttle or nothing), but when the power switch is off is just turns it self on and goes full forward. What do y'all think is the problem and the solution.Thanks! eps

Sounds like blown fets. Mine acted the same way. Get a 2X3 stack. You won't regret it:)

How the **** can fets blow in a ****ing day!

And I should add i looked inside the beast and couldn't see anything wrong with it, like scorching or anything. hmmmmm...

It doesn't take much. I was running mine up and down the driveway at full throttle and it basically overheated. I had one small blister on one fet. I've blown fets in racers with no visible damage at all.

is the servo/steering workign at all?

that is quite odd that it powers the motor whenits OFF... that should not happen... even if the fets are blown.

It sounds like it was wired wrong durring assembly... or maybe you got it from some one that damaged it and tried replacing the PCB in it... and they did it wrong... lol.

Yeah, if you have steering but no throttle the fets are blown...Unless it's abad motor connection. Anyway, you can also just do a 2X1 FET replacement.

It only takes a second to blow FET's if you are overloading the car. If you tow things or pin it against a wall or run a motor that's too hot, you can fry the FETs.

I think there is a picture of a blown FET here (http://mini-zracing.com/blog/_archives/2006/7/11/2093568.html) There's also some good information about FET stacks, replacements and turbos...

Mine was done by the shop. Took about two weeks there and back. Nice clean job too. Good luck with it!

Could the shop install a Nelly stacked turbo for me?

I don't know if the shop would do it, but maybe PH2T would do it for you. He is the one that sells the nelly's. Email him and ask.
