Speaking of 16 volts.....

[Ed Wright]

Anybody ever check for AC voltage out of their 16 volt charger?
I have always downloaded my FAST internal data logger, and made any tuning tweaks while the charger is running. At the Noble points race (last one for Div 4 each year) I lost one MSD box and two FAST XFI ECUs before I think I figured out what was happening. Think the rectifier in my charger failed. It puts out 40 volts AC!
Evidently time for a new charger.

Thanks to Slate Cummings for loaning me his spare ECU so I could race. Attempted to anyway. Bye first round, went red second. I really suck. LOL

I have had problems with the XS & turbo start chargers, found the Moroso 12 & 16V the best.... they are heavy duty!

Cool! I will check on that. Need to make a change. Handy to have one that will charge both. Had no idea anybody made one.

Thanks Tom!!

I always have the power to the car turned off when charging the batteries to prevent those types of problems. Dyno

I turn the batt off now. Didn't for four years. Then all that carnage in one weekend. Has anybody else checked their 16 volt charger for AC voltage? When an automotive alternator does that it's because the rectifier failed. That converts AC to DC. Not sure about a charger.

MSD replaced that box, FAST fixed both ECUs. Kinda pricey weekend.

I turned the master cut off switch off while Slate's ECU & my back up MSD box was in it. Have not had another race, but will do that from now on .
Scared of that charger now.

Ed,

I've popped the MSD high end chip a couple of times when charging with the main switch on. Only happened when the charger to the post connection was "sparked" by someone plugging in the charger first or accidentally knocking it off while charging.

Beat yourself up if you chose but at least you have friends willing to help you when you need it. Friendship ends in the water box !

Lots of good guys racing in a Div 4. Great guys from Louisiana.

Yep, none of the Cummings guys cut me any slack. Beat me like a step child. Think they could go easy on an old guy, but Noooooo.

Thanks!
