Re: looking for wire diagram for updated cdm conversion for a 96 mercury 120xr sportj
Well it took a long time before i started to andustand this Wes Craven nightmare.
Don?t andustand why they had to complicated it so mutch.
Stator i andustand, becaurse if one of the coils to two CDM is dead, you shall be running home on two cylinders. So far so good.
It?s own power i good too if battery is dead, weak. But i tried to start mine with a string. Just for see ift its possible, if stranded on sea. Well i?m 195 cm long and 100-110kg ( gun)-smith. And i can tell you i could not turn it over. And you need to get it up a little in RPM to give start voltage on stator.
And another thing on mine. Put new reticif. on becaurse old burned. And it ground in coil plate, that are rubber mounted ???. So i run a fat negative wire from Reticif. to a good negative place (engine, neg wire batt etc.) Otherwise when battrey low on AMP , it will put near 19 Amps to the plate where CDM sits, and not so good grounding in engine block.
Now the big :facepalm:
!!!!!!!.
On the CDM models one CDM helps the other and are back slinged in wiring trough another. Wich will make a good CDM if you unlucky, to not work if one other is bad. They are also poltegeisted becaurse you can get good reading of them but the anyway will not work propebly.
Make shure your CDM ground to engine is good ( 2 on 120HP). There i had a gost-problem in mine engine. Worked okay low rpm, but throtteling up it would start to missfire. Found it out when testing the D********* boat out for the nr 550 round in sea. Had all wiring just loose on side and started to pull in all wires with engine running on idle. Then it started to missfire. So i solderd new connections on ground wires.
And never disconnect the battery when engine running. You can kill electrical komponents. It can be trouble if you have a battery kill switch too. If you turn it when engine running. Ore a switch between two batterys.
