HHB pma high voltage?

[burns]

I had this situation when I installed an RD based PM charger. One of the wires coming off the R/R is for "feedback". If it is not pigtailed into the output wire the Regulator will not "know" what it is putting out and will go to "max".

I understand that some units put that feedback circuit directly into the R/R.

I suggest that you identify the purpose of each of the wires that is coming off the RR (not the input side from the stator but the output side) and double check that they are connected properly.

For a test, try your volt meter on your car battery.

It should read 12 - 12.3 volts and no more. Car not running of course and nothing turned on.

Could be a faulty meter.

I just checked my daily driver...
NOT running, right on the battery posts 16.4 vdc

better late than never.

Well that was easy to fix

So... you guys are suggesting the meter is bad? Well, if that's all that it is great, but I'd really like to verify this somehow before I hook up the Pamco and my headlight....

Yeah in 20+ years of working on cars, ive NEVER seen a battery read 16+volts on the posts when not running... crapsman strikes again. Unless you live near area 51, you got a bad meter.

 

[RCGRT]

Well isn't that interesting....
So for future reference, how does one calibrate a multimeter?
In the mean time (it's not my meter, I think I know what my next toolbox toy will be)
Any suggestions on what brand I should look at getting?

RCGRT,

Make sure you have selected the DC Volts range. If you select AC Volts, some meters read high when measuring DC.

Pete, if you look at the picture of that meter, I think you can see where I have the knob positioned. But I'm 99.9% sure I've been using "Vdc" setting

OK. I see that now, but what's that little battery symbol in the lower left corner of the display?

Pete, I'm not sure what the little battery icon represents, but I did just notice, that little battery icon stays on at every position, even Vac??? (evey position except OFF)

Also, I just dug up an old analog vehicle analyzer that has a voltage setting, hooked it up to my test battery, shows 11vdc, started the bike, shows 14.5 -15, it was moving around a little, but the dial stops at 16 and it certainly wasn't pegged out....

Put a new battery in your meter. That should be the low battery indicator on your screen.

Ahhhhh..... I'll see if I can find one! Thanks, we'll see if that makes a difference...

 

[jriehl08]

I just looked it up on sears.com for that meter it is the low battery indicator

 

[RCGRT]

Oh ok, cool, thanks. I'm going to pick up a new one and give that a try

Hey RCGRT, I just wanted to add that a lot of automotive parts stores loan out tools, you might be able to grab a meter there for free.

Ok thanks, if the battery doesn't change the reading, I might try that. Looks like a quality meter can cost 50-100+

Harbor freight sells one for like $6... they work fine testing simple stuff. I use a equus multimeter, ive checked it against my friends fluke (hes an electrician), its exactly the same... just fewer capabilities.

Got it on sale for $12, down from $40+

No problem man hope a new battery fixes the high voltage readings.
