A lot of auto parts stores do load testing for free.
Call around.

Peace!

ok ill do that. probably just gonna get a battery too cause in a month or so ill be seeing 100degree temps daily.

the roads are filled w dead cars down here in the summer months.

a load test would test voltage or charge w a given load(accesories running) right?

when i disconnect my battery...do i need to do anything w the gryphon, keep it installed or unplug it, anything like that?

I'm VERY glad you asked that question!

PLEASE, disconnect your Gryphon before you disconnect the battery! Leave the Gryphon disconnected as the new battery is being installed. Voltage transients that occur when a battery is reconnected (or when a vehicle is jump-started) can fry the electronics in a pre-04 Gryphon's OBDII cord and, they don't do the post 04 Gryphon's internal electronics any good either. Finally, when everything is hooked up, turn the ignition to ON without starting the engine, and then reconnect your Gryphon to the OBDII port.

I wouldn't have the Gryphon connected during any load test on the battery either.

In other words, anything that can put big fluctuations on the DC voltage in the vehicle can harm electronics like the Gryphon, probably sound equipment, and maybe some other things.

This information needs to be included in the FAQs on PHP's website and we need to make it pretty obvious here too. I'll see what I can do to make that happen.

A load test essentially measures the battery's voltage with a high load (like starting an engine) applied. It really needs to be applied to a battery that has "rested" for a while after any recent charge, so that the "surface charge" has had time to bleed off.

OK, I've just added a new "sticky" in the FAQ section of this forum that warns people about leaving the Gryphon connected when large power surges can occur on the vehicle's circuits.

Because of the keep alive memory feed, the only way to isolate the Gryphon is to physically unplug it (or pull the circuit breaker that powers the cigarette lighter and OBDII port).

glad i decided to wait on that one. and yeah it does need to be added to the faq page, i looked there the other day but didnt find it.

thankx for making that clear.

i watched my bat voltage over the weekend and i had a min reading of 13.6 at like 50-55mph, and a high of 14.2 at 60-70mph. most of the time it was between 13.9/14.2.

for what its worth i turned my key on before starting the trk the other day and the voltage was at 12.2.....this morning i noticed it while cranking, it was like 9-9.2.
thankx agn for the info.
