1993 190 DCX Elite.
On ocassion I have a power drain when cranking or trimming the motor. It stops if I disconnect either lead that supplys power from the battery to the console. Also if I jiggle the wires were they run thru the conduit. Once, when at full throttle, and in light chop, the problem killed the motor instantly. After messing around with the wires all was good again. It seems like a ground problem, not shorting out with the positve side though or I think the wires would heat up and brakers would start popping. Maybe the ground is bleeding between the motor and boat power causing a drain off. (finding a different ground source?).
Does anyone know if the main ground wire running from the battery to the console has other grounds spliced into it along the way i.e lighting gnds etc? I tried to replace the gnd wire but I can't isolate where it comes into the console. When pulling on it (slightly) from one end, there is no movement at the other leading me to believe there are other gnds attached? If I can isolate it I will run a new wire. I may have to pull the fuel line from the aux tank as it seems to cause an obstruction from pulling new wires. What a paine! Any ideas would be a help. Thanks
