Re: Suzuki '87 150hp charging problems
u need to get a meter
find your starter solenoid
find i think it is white, or red white, that is battery charge
find the fuse and check it
no plug the red lead on the meter to the wire that goes to regulator/rectifier and black to ground
either start or crank motor, u should see 13 plus volts if running, around 12.5v if cranking
u could have a bad reg/rectifier or bad battery charge coil
do u have the manual, if not get one asap
