Mercury 70hp Outboard Startup Youtube Re: mercury 70 hp outboard stator question. i replaced stator on a mid 70's (4829645) 70hp merc . original stator pt#398 5704a2 with cdi part #174 5454k1 . install instructions "mark position of the mounting screws in relation to where the stator wires come out of old stator" . "orient and install the new stator in the same position as the. 3,270. dec 8, 2008. #1. testing the stator only requires an ohmmeter, you do not need to remove the flywheel. disconnect the yellow leads to the rectifier. disconnect stator leads from switchbox. engine should be cold, resistance increases with temperature. specifications are from a manual that only goes up to 1990.

Disconnect the mercury outboard switch and reset, if the engine fires, replace the mercury outboard switch. check the voltage on the red and white ignition wires at the cd unit. if the voltage is less than 9 1 2 volts during cranking there is a problem in the battery s or the ignition switch box. Mercury mariner dva (peak reading) and resistance charts. (excludes japanese mariner models) performing tests on ignition components requires that you have the proper equipment to do so. this chart assumes you have the adequate testing equipment to diagnose ignition problems. understanding this chart: example: grn = green wht grn = white green. Therefore, you must detect the signs of a bad stator. the most common signs of a bad stator in a mercury outboard engine are problems with engine activation, lack of power, and misfiring. plus, if the battery fails to charge continuously and corrosion build up around the stator’s surface, rest assured that the stator will become faulty!.
