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?

Not even on their website? Many companies have them there.

88.8 sounds like testing the display (all segments lit). However, it
shouldn't stay that way more than a couple of seconds on startup.

Are you sure it's connected right?

I don't have that model, but one battery charger I have refuses to
work when the battery charge is too low.

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.

Ah, thanks.

No, the whole unit is locked up. You have to unplug it and plug it
back in, then it resumes. It's up to 70% charge now.

I've used the charger several times before and never had this happen.
I hope my battery isn't done for. I just spent $500 on a new
alternator and another $100 on a new battery for my Explorer.

I usually put a battery tender on my Mustang in the Fall...just forgot
this time. Funny, considering I washed it, filled it up, put fuel
stabilizer in it....
