70hp charging system

i have a 1996 70hp force ,,i believe it have the thunderbolt ignition system on it ,unfortunatly i only have 1 volt comeing out of one of the yellow charge wires but 6 volts riseig to 12 on the other ,,from the rectifier/regulator i have onlt about 1 volt comeing from the red charging wire but 6 riseing to 12 when reved from the grey wire which i beleive is for a rev counter ,,could i safly connect the gray to my battery to use this for charging ???or .......i have a older ignition system from a crysler ,,could i use the stator from that ,,or the stator and trigger ,,,,,,or would this not work with my controll box ,,,any help would be very king ,,thanks
 
Older stuff probably won't work on new motor.
outboardignition.com has test procedures for all outboards.Go there do the tests before you buy any parts or change anything.
Get back with the results.
 
there should be a beaker or fuse. Check those and if the check out proceed. you should get 1.0 amps @ 1000 rpms output min and 9.0 @5000rpm max . stator ohms should be .6-1.1. this shouldnt be a thunderbolt because it was put on 90 hp and up. Is the Tach working on this motor? It counts the ac voltage pulses before its rectified to dc volts. so therfore not working properly. Battery couldnt be totally dead and not wanting to take a charge since your using it to start and run motor right? dont disconnect battery leads while motor running this could cause the rectifier to fail. Also dont change the poles either. this could cause the same dammage.Check all connections in the charging system and use di eletric grease to protect this makes a differance. Do this and get back with results.
 
dont move wires around and use the parts defined by engine make model and year by the way. There is a reason they made this that way from the factory. Just food for thought.:)

the rev counter seems to come from the rectifier ,,i dont have a tacko but it measures 6 volts on tick over and 13 when reved ,,the battery is fine ,i stick the volt meter on the yellow wires befor the go into the rectifier and one reads 1 volt and the other 6 volts
 
When did you rebuild? Is it after rebuild you have been having problems? Check to see if you put the stator back on right. They can be put on wrong.
