A lot has happened in the month it took for my banggod kit to arrive!
I decided to try and assemble the stock kit to make sure it worked..
Bloody hell it worked 1st time!
I didn't bother trying to read every post on the past 10 pages as it seemed to be a lot of troubleshooting.
I saw a pic in post [URL="https://www.badcaps.net/forum/showpost.php?p=669432&postcount=273"]273[/URL]
I take it thats what I need to do to hookup my usb programmer?
I have a couple lined up GM328A or GM328R ?

Hi all, is this one any good to get ? gm328r[url]http://www.ebay.co.uk/itm/2016-EZM328-GM328R-transistor-tester-ESR-frequency-meter-square-wave-genera-/331873741389?hash=item4d45376a4d:g:rrsAAOSwtJZXU~VA[/url]
or should I get the gm328a? [url]http://www.ebay.co.uk/itm/2015-version-GM328A-ESR-Meter-Transistor-Tester-Diode-Triode-Capacitance-LCR-/221860478238?hash=item33a7ea3d1e:g:EskAAOSwHnFV2EJw[/url]
oh hell yeah, the calibrations been out for a long time, I never clicked onto this being a no charge fault until last week and means it has been fubar on the voltage readings for a couple of years, I loaded it to 30% as per the suggestions by APC forum staff, kept the load stable and did a test, it would drop from 6:21 (stock no load with new battery time) to under an hour and each time I tried it the time would get lower until it just failed every attempt.
New ups in, 30% load, calibration ran for over 90 minutes then came back...
I don't have one & have not let the batteries drain that low as the unit shuts down when they hit 10.5v under load, that raised back up to 12v per battery or 48v total where is sat overnight doing nothing apart from saying the capacity was going up when not a lot happened as it shut down in under 2 minutes where 100% charge went down with no load to nothing in a minute.
Looks like I will have to invest in a ESR meter to progress then?
Any suggestions for something cheap to do the job?...
If you go back to the 1st post the controller reads 6 volts higher than the actual battery voltage, the main fault I am looking for help with is an error in the sensor readings.I would like to figure this one out before anything else as it may be the reason it isn't charging, if not it is a good start as it will never bulk charge if it thinks the batteries are 6v higher?
This falls in line with a fully charged battery triggering the charger over voltage warning as it is reading 60VDC+ via the sensor.
To be fair the new one doesn't charge at a high voltage, it brings them up slowly as you will see with the attached log, from the bottom up I took it as it finished it's runtime calibration back to the final voltage.
I will put it back together and see if it is offering a charge when I get the chance. my fluke DMM is rated to 10a, is that good enough?...
The diodes at the back of the battery cab, I think it is meant to touch the rear pack as it sticks out. It has read around ambient (it reads 1-2 low on the room) for a while now, probably due to it never charging. It lives in the dining room so no major temp variations although it spent its 1st 4-5 years up the loft powering my former office. (new 2200i is at 54.3 VDC fully charged)
When I 1st turn it on it spikes to around 55v for a second then quickly tapers off to the battery voltage and stays around there. I don't hear it throw...
