io was installing a friend of mines car a MSD 6AL with the rev limiter and it works fine but the rev limiter doesnt work. we put a 7k rpm pill so it doesnt past over that and it did. my question is what i did wrong? thanks

 

Did you cut the two wires that set the unit for 4 (2 rotor), 6 or 8 cylinder? They are under a plastic cap held on by a screw.

I just installed two 6AL's and the rev limiters work great.

 

are the dip switches set for a six cyl? just as well it doesnt work, he would not like the ign. dropping out anyway at 7K

 

i think my friend did cut the cables inside the cap. because he told me something of that.

rototiller1: what the dip swices your talking about?

ohh and BTW. i forgot to mension that it is for a 4 cilinder car, i didnt wanna mension this because i dont want this tread on another place so please dont move it. thanks

 

There aren't dip switches.

-Veryify that the two wires are cut and not accidentally touching.

-try a different pill, a very low rpm one, I think a 3k pill is also supplied with the 6AL. Try the 6k pill too.

-ohm out the 7k pill, it should be approximately 3.14k ohms.

It is possible, but very rare, that you have a bad box.

 

I'm sorry my mallory 6al has dip switches

 

You would have to install two separate msd's, one to limit the leading, one for the trailing. It is probably cutting the spark to the leading and the trailing is keeping it going.

we tryied the 3K one too and it still doenst work. i didnt have much time to check if he did cut the wires so im check the tomorow. thanks
