I have a Schumacher Speed Charge SC-7500A battery charger.
I put it on my Mustang yesterday.
It keeps "locking up" with 88.8 displayed.

I can't find the manual.
Anyone know what's happening?


Well, the manuals are here;

However, a search of "88" showed no finds. I would be inclined
to believe the digital readout is stuck. Have you tried
unplugging the unit a few times to see if it will clear the
registers? It reminds of when you see digital readouts where
the LED part has burned away; but yours are stuck in full
readout. *8* being the full circle of LED's.
