WIRING DUAL AMP VOLT METERS

After getting back to work from the Holiday, my work load was light and the weather outside was great, so ended up taking a day and a half off to work on the Fiero.

By Wednesday evening one of the duel meters was working, so I did a short video.


PACK DUEL METER WORKING 

Later on Wednesday evening, I started putting the LED lights in the instrument panel. The lowest wattage bulbs were not bright enough, so had to go with higher wattage LED bulbs. Then I blew a fuse while trying to get one of the bulbs in, so will need to go get some fuses.

Thursday morning I called Hebron Scrap and confirmed that they were open. The said they were, so the car was loaded up and off I went to unload some junk. Surprisingly, I got $63.00 for the pile that had accumulated in the Better Place shipping crate, so I put it in my fund to buy new leather seat covers.

Then a shunt was placed on the negative side of the 12 volt battery and connections were made to the lower duel meter in the instrument pane. While trying to remove the drivers side, front blinker light socket, my arm touched the battery pack and chassis ground, giving me a little jolt. Great! All I need is a battery leak to ground. When I was hooking up the low voltage duel meters, I hooked the red wire to 12 volt positive. This was a mistake because actually the red wire hooked to the pack 120 positive side of the shunt, and I fear with the ground leak, blew the high voltage meter 12 volt power supply. Anyway, only the lower meter is working now, so I ordered another meter from EBAY. When the proper wires were hooked up on the 12 volt meter, It read 13.8 volts but I could not get a current reading. Not sure if power is feeding through the dc-dc converter ground and not actually going from the battery, but I will need to do a little more work to try and get a reading of some kind from the 100 amp shunt on the 12 volt system. 

Hopefully I can get the meter that is probably blown out of the instrument pod by removing the face, as I am not thrilled about the possibility of taking the instrument pod out again.

The right angle micro a/b USB arrived today, so I will also need to work on getting the USB wire run to power up the Dell Venue 8 Pro.


MICRO A/B RIGHT ANGLE USB CABLE

A refurbished Powerlab 6 was ordered and should be here in a couple of days to do the second bottom balance of the Better Place module. All of the cells have been brought down below 2.8 volts but have drifted back to 2.85 or so. The Powerlab 6 will allow me to set a much tighter voltage range and I can let it set and cycle at a low amperage drain to try an being them all in line. I have a multi cell cable but am not sure if that will allow me to bottom balance 6 at a time, so will need to play with the Cellpro for awhile to see if that will work. If any of you have used a Cellpro with the multi cell connector to bottom balance, shoot me an email at randy@cz-ev.com

Thanks for stopping by,
