At last mjl installed and working fine...thanks to MartinM (really recommeded him if you get stuck like I did)... Turns out rs232 chip was kaputt - replaced, and now ok... I have loaded a base map (2.0 pinto - twin 40's / mild cam) and this seems to do ok. I am planning to get the car onto a rolling...

All, I have contacted some one who can fully test out the megajolt for me, and hopefully make some repairs as necessary.. MKnight702 - yes I followed your thread, and tested the values around the board aswell just incase, but no luck there unfortunately.. I will keep you all posted on my progress......

brent,
I have seen some posts about dodgy capacitors, or even wrongly valued ones is there a way to check this or am I barking up the wrong tree?

Brent,
measured pin 9 - readings are
running - 0.02vdc (0 vac)
standing - ignition on - - same reading 0.02 vdc (0vac) ?

I suppose this means the chip is duff?
What do i do to replace? if necessary


regards
Simon..

Brent through powers of deduction i have managed to work out the pin numbers using the schematic and data sheets I found on the web supplied by component distributors etc. Readings are as follows: pip voltage - mjl disconnected (not running) - 12.9 vdc pip voltage - mjl connected (still not running)...

hi brent,
yep please can you identify the teminals i need to measure, i know where the items are but at which location the pins numbers start / stop isnt clear to me thanks

ok. have been to scrappy, and sorced another edis module - car running at 10' . now just like the last one i have still got arund 2 volts going into the mjl down the pip line ? the run time display stays at 457 rpm, the TPS indicator (thats the model i am using) is working. The mjl is reading / writ...

Brent, this morning i rechecked the pip voltage coming into the mjl and i actually found it to be around 2.6 as oppsed to the 4.5 /5v you had quoted? doe this mean Edis again, I have againg checked the voltage goes onto the board. i did'nt assemble the board, but i have taken the time to read throug...

thanks for the reply Brent.. I firstly double checked the connections are in the correct place and I have checked the pip voltage coming into the mjl and its around what you say.. I double checked the voltages / connections make it all the way inside of the MJL aswell. I can communicate and read / w...

It Lives ! At last finally found time and replacement Edis to try & Bingo...sparks galore and engine running at 10' no problem...I have connected MJL but I cannot get any rpm readings on software, or any ignition advance at this stage. I have connected a volt meter and I am seeing a volatge goin...

Hi there again, found time to do a little checking... as suggested double checked connections especially polarity / supplies , even went as far as the wiring diagram in the car manual for the donor. Everything checked out ok. I reversed the polarity on the VR sensor to no effect? checked distance to...

Thanks...
by reversed 12 v supply do you mean wrong connection or possibly wired differently ?

Simon.

Help! (first timer) I am experiencing a lack of spark on my mjl installation. I have taken the advice of installing the edis first to ensure 10' limp mode is working etc, but it is giving me any spark whatever, have tripple checked wiring and supply voltages etc. Even tried different coil pack &...
