Reply To: Charging 85 hp 1972–upgrade stator?

Me too, don’t ever recall having an issue with the battery CD charging systems…
Have you put an ammeter inline to check the actual output?
Keep in mind that there are two other items that tie into the alternator output that could have an effect…
The shift diodes….These diodes AKA “monkey balls” are tied into the stator to supply current to the shift solenoids so the engine will stay in neutral when the key switch is turned off and the flywheel is still spinning…A quick test is to shut the engine off while at high idle in neutral…If it slams into forward gear before shutting off, there is a problem with the shift diodes…
This engine also has what is called the “clipper circuit”, which is really just a basic regulator…The clipper circuit kills half the alternator output if it senses high voltage, such as a loose/corroded battery connection…So, if this unit is messed up, you will only get half of the alternator output…But, keep in mind, the clipper might actually be doing its job because it is sensing high voltage!

Again, I never encountered an issue with these 9amp systems not keeping up with basic electrical needs, so I would check the items I have mentioned before investing in an expensive larger output stator…Would love to see any info you have on this kit, don’t remember anything like that being offered…
