Yes it does = engage the gear=20 so I did wire the two solonoids in parallel on the activation wire but = I=20 disconected the battery cable from its' normal input side of the mazda = solonoid and put it on the side that has the cable going to the motor. = This=20 way (I thought) no current is going through the mazda solonoid = contacts. =20 In spite of my being convinced this would solve the problem, I regret = to say=20 there is no change: stays running after starter switch = opened.

So doesn't this have to mean that power is = getting from=20 the contacts to the coil of the solonoid???.

Peter,

I presume you = have ruled out=20 any problem with the disengagement spring on the starter that pulls = it back=20 from the fly wheel after the power is removed. If not, = the=20 starter may remain engaged even though there is no power to = it. =20 If a Mazda starter, power to the solonoid drives a lever which = pushes the=20 gear out to mesh with the flywheel. There is a spring in the = solonoid=20 that is suppose to retract the gear drive by pulling back once the = power is=20 removed. If broken or stuck then the starter will not readily=20 disengage even without power or if the lever arm that actually = engages the=20 starter shaft is binding you could have the same problem. = Adding=20 another solonoid in parallel won't help - if this is the=20 problem.
