Save yourself the trouble and please shut off the master switch when charging the batteries. If the charger spikes, it will take out all kinds of stuff

the alternator should not charge voltage that high. If it does check to see if it is adjustable. Anything over 18 will likely spike a Fast ecu driver

That voltage is what I have read online. Alternator is adjustable from 13.5 to 18.6. My thoughts were to set to 16 volts and charge between rounds with switch off. I figured anything much above 16v would start frying things. Manufacturer of Electric fan (Deraile) states it will burn up at 16v.

I realize that point. My main question was at what point of voltage would you be concerned about component damage running with an alternator to charge the batteries.

You shouldn’t have any issues mine charges at 18 with the powermaster adjustable alternators and really don’t need to charge it. I would suggest checking your alternator rpm you may want a larger pulley to prevent it from spinning too fast. Since it is adjustable if you would prefer to lower the setting to around 17.2-17.5. However, under a load it won’t be that high.

Turning off the charger while cranking solves this. Some smart coils (IG1A) have issues over 17 volts. They can shut off. Most of the GM smart coils are ok. Robin
