thanks for your reading
I have merc classic 50 4 banger circa. 1985
just replaced the ignition switch on my new remote control.. used the sierra Mp41070-2. listed as a direct replacement.
I also did a retrofit for a newer rectifier with regulator.. cdi 193-5114 seems like a steady 12.67 voltage reading but need to take my meter out on the water to see what higher rpms do..
after loosing my cdi box to a faulty switch I exercised due care on testing voltage to the kill wire. So to test I ran the motor with kill wire
disconnected. Results below.
With the ignition key in the off position, engine running or not.. .05 volts
With the ignition key in the on position, engine not running .05 volts
With the engine running and the key in the run position .5 volts..
With the engine running and the key in the off position .05 volts..
I did not see any continuity using my digital multimeter between the terminals at the engine side connector but still get the juice to the kill wire. The controls are new.
I read 12.67 volts at the battery and at the engine..
Switch leaking juice across terminals??.. its one of those sealed pods
read numerous tidbits on this.. CDI, the company cautions to test and sets a limit at 2 volts.. though I also read that any positive voltage
to the ignition box can cause damage....
right now i have a separate kill switch wired.. works great but its an extra switch and some extra wires.
anyone else test this stuff and have similar results?
is the rectifier update pushing more juice that the system is designed for?
is this commonplace and normal?? I just spent a bunch on replacing most of the ignition and charging and don't want to do it again..
Thanks in advance for your thoughtful replies
