Obviously the meter is not setup properly if you get 7-800 on a 144V nominal system. You should be sitting around 165 fully charged.
*where would I see this figure?
How long was it sitting plugged in?
since I was told to leave it plugged in any time not in use[builder/previous owner] I did ,all summer here w/temps up to 118 .I put box fans under the trucks bed area and in the front grill since 3 batts are in front ,so every time I opened the hood always had cc showing and w/my minimal ev experience and having numerous mc's all w/battery minders it stayed on all summer til it cooled off and now its going to be my only pick-up I knew to get ac back in soon and that's when this was found ,dry battery's and all.
F3 is a gas and float mode, so it will act as a battery minder, but depends on the d value as well. To check that you can disconnect the charger circuit (on either end or in the middle if you have some disconnect) and plug it in. Press the button until it shows the F value (F3 you said) and then the d value.
thanx, will do asap!
* meaning charge and dis-charge over and over and so if not programmed correctly this is the outcome ,drying the electrolyte out entirely even tho cc showed all the entire period til this .
As for the jerkiness when trying to start...what controller do you have? Do you have a DVM to check voltage on the entire pack? Also you can check (with the car off) the values coming off the throttle pot for it's full range of motion.
yes, have DVM ,checked yesterday and each cell shows approx. 6.7, but dont recall how long it had sat off charge
how/where would I check the values ,what should I see there ? what am I looking for and why would those have changed when no adjustments have been made at all since getting it last summer when it drove back home from picking it up from the shippers location ,just a few miles but enough to really get me excited about the future for conversions . I'm working w/some folks currently trying to get a school together in dallas to teach current mechanics familiar w/auto electronics this field of study so they'll be able to teach to students to start careers in this field as the ev becomes more known about . I really feel like the private sector ,little guys are to be the ones to carry the torch ,to bring conversions into the mainstream . If thru this a biz becomes available I'd like to involve my 40 year old son . The hardest worker on the planet 22 years same job at the top of the profession and he'll be a great teacher after he can get educated on ev's . Had thought about using this truck as a basis for advancing this idea going forward . well, nuff of dreams .
Really appreciate your help
Guess I've got work to do now and have NO clue as to why and how this occured.
