MJ Hard Limiter Wiring
Turbo Mini Forums

Upgrading my MJV3 to a V4 with the new engine, and with the one i bought it came with a hard cut rev limiter.

It didnt however come with the instructions on how to fit it, and i think i'm missing a transistor.

So i have this on the Hard Limiter board:

And this on the main board:

I'm assuming i just link 3 of them together, the GND to GND, COIL to COIL_PWR + and TRIG to AL_TRIG

SO where does the +12V go? And what value transistor do i need for the Limiter board?

Thanks

i cant help but once you've worked it out can you post a piccy of it wired please. as i have it on mine but it dont work so wanna make sure they did it correct.

ta

that transistor looks to only be required if the surface mount transistor sharing its pins isnt man-enough. I could be wrong as have know working knowledge of the mega jolt setup but thats what it looks like to me.

turbo 16v k-series 11.9@118.9 :)

Ive done it the 4th is at the other side of the board,

I think its the mj's 12v feed, just solder ur wire onto it

13.95 1/4 mile on a 2.95 fd. Carnt be that hard to beat!

cheers, just found the search bar on the autosport labs website and I think I've got it.

The big transistor isn't needed, and is only used on home built kits to make it easier. The small one attached to my board is the right one.

I'll put up a few pictures of it completed so if people find this through a search it'll be here

i fitted bennys with no instruction the 3 solder pads in your photo are clearly labled coil power, trigger and ground
the 4th is on the top side ( just off pic) and is 12v

Yes i moved to the darkside
