Some may recall I was reading almost full pack voltage between my traction
pack + and the chassis. I discovered that this phenomenon went away when I
turned the key on. I had installed a relay to protect the precharge circuit
of the Raptor from charging voltage. By removing this relay and leaving the
precharge connected just through the 60 watt current limiting light bulb,
there is no voltage between pack + and ground.
So, I solved the problem, but have no idea why this should be true.
Now I have another related problem.
I have an old transformer based charger in my garage that I use for charging
the batteries. I also have a transformer boosted "bad boy" for an on board
charger. To insure a modicum of safety, I included a GFI into the source for
the on board charger. A secondary use of the on board charger is to increase
the charging rate since I can plug it into a different circuit and run both
chargers at the same time. I have done this a number of times in the past
and it works fine.
Today, I plugged in the bad boy and the GFI immediately blew. I turned off
the big charger and the bad boy worked fine. When I unplugged the green
plug on the Raptor controller, the two chargers worked just fine together.
The pack under charge is at 167v and there is now 108.8v from the pack+ to
the chassis with the green plug removed. This is also strange since there
used to be almost 167.
I'm befuddled.
