double check your jumpers to this:




and you adjusted the two pots?

 

I double checked my jumpers and it looks exactly the same.

Yes I readjusted them one more time for safe measure still no start.

 

take a COMPOSITE log during cranking now. (under diagnostics tab.)

 

Ok I will do and post results when I get home in a couple hrs.

 

Composite log attached. Thanks for all your help guys.

 

no crank signal.

 

I have no idea what to do at this point I read online the pots may need adjustment but it doesnt seem to help at all still no signal.

EDIT Also I was never able to feel the "click in the pots" like everyone mentions

 

Is 5 and 6 suppose to have volts. I took my multimeter and I was getting volts on everything on J1 except 5 and 6.

 

it must have been your adjustment of the pots.

the crank signal comes in pin24, which is tachin. This goes to the JP1 jumper and that should be on 1-2, that should have been changed from 2-3. Then the signal goes through the VR conditioner circuit and those adjustment pots, and then out to J1 through 5-6 which sends the signal to the CPU. This should have been moved from 1-2. Right?

you need to spin both 6 turns CCW, then turn the bottom one, r56, back two or 3 turns clockwise.

 

Yep. J1 was moved to 5-6 from 1-2. I should have got a stimulator

I think I may try and see if I can try and measure with a multimeter any signal on 5-6 so ideally I can see if the pots are allowing signal through. Ill be back with results.

 

You'd have a tough time plugging a stimulator into the MSPNP.

You can measure the top of R54, you want to see around 2.5-3v when turning R56 back Clockwise.

 

Sweet so I was able to dial in the pots with the multimeter(so I think). Actually if anyone knew the exact v's on both that would be sweet but nonetheless the pots are working. I still have no crank signal and 5-6 shows nothing as far as v's or analog resistance.

 

R52 has been turned CCW at least 6 turns?

 

Yes sir. I turned R52 six turns which removed all signal on the multimeter. R56 has about 2v when roated CW two turns.

 

get it closer to 3v, then see if you get the crank signal on the composite log. Cause that's the only thing holding you up, the rest of the jumpers are unrelated and youre getting the cam signal.

 

Why..?

 

you can do that, I typically will just use wire with the correct female contacts to bring in power, ground, crank trigger and the second trigger to sync on a DIYPNP or MSPNP.

 

Still no crank signal. I tried it at 3v, 3.5v, 4v, 4.5v, and 5v. Still nothing. Something else in the circuit has to be wrong. luckily I have been using a gel cell optima battery out of my truck or the battery would be dead by now.

 

There's not much to it:



Pin 24 (the crank input) is Tachin.

that goes through the VR circuit and out to IRQ-1 (cpu), so the only thing to it is the two jumpers and the adjustment of the pots.

The JP1 2-3 jumper and J1 1-2 jumper should have been severed, else that would cause issue.

 

Could there be any resistance elsewhere that may need to be changed? Maybe a different ohm resister or something?
