Sounds fortunate that Ford only charged $700. I've personally seen diagnostic attempts cost $1000 with no resolution, and many dealers will quote a minimum of $2K for the charger due to charger rental and minimum days required for rental. I wonder if they happened to have one on site.

 

Yes, they had one on-site as they complained how horribly expensive that it was to buy. I have a problem with the battery losing charge overnight, fortunately not enough that the engine doesn't start. I'm hoping that your suggestion for charging the battery to 100% and running on HEV only after the gas engine cuts off will help with that. My DEL_MOD_V = 0.19V.

 

First time poster...kind of like others, I signed up to say thanks to S Keith and the rest of those on this forum that were so helpful so far (my vehicle is a 2009 FEH). I've got the back compartment disassembled to the point of trying the vestigial connector, with battery in place, method. I just got my HLG-120H-350A and am just waiting on the diodes to wire up the charger setup. I'm thinking of doing as a few others have recently and leaving the setup in the battery compartment and routing a short extension cord out in case this happens again.

Any worries with just clipping off the vestigial connectors and wiring directly (solder or otherwise) in from the output of the charger? Can't imagine those connectors would ever be used. Any other precautions/advice for a "permanent" charger being left in place?

 

That's what I did when I wired mine. I zip tied the connectors to the wire so I would remember gray=positive, black=negative. Probably overkill on my part.

 

What type of fuse did you use on the input side? I've spec'd out the diodes based on the threads above for the output side of the power supply (https://www.digikey.com/en/products/...N4005G/1485476), but I didn't see a good recommendation either way for the fuse (or if I really needed one with the HLG supply; could just use a power strip or fused extension cord whenever charging).

 

I didn't use a fuse. I just plugged it in to a surge protector.

 

I want to do the same thing you did and leave the charger in there as a precaution attached to the vestigial charging cables, and I just want to confirm that you didn't use a diode at all, correct? and there are no problems with that? I already have the C350A power supply, I'm trying to figure out what else I need. As useful as this thread is, It's a bit unclear how to wire the charger to a layman like myself. a rudimentary wiring diagram would be useful from anyone who has successfully done this. Thanks in advance.
EDIT: I realized after looking over the thread some more and doing other research, that I do indeed still need a diode.

 

I used the wiring diagram from Post #99 which I've pasted the portion here. I used diodes between the power supply and the HEV connection cables. I ordered 6 diodes; 1: They are cheap, and 2: I'm a klutz and I screwed up on my first pair. I used junction boxes to protect the diodes but anything would work.

 

I didn't use a diode on the AC power cable.

 

thanks for this, exactly what I was hoping for. I must have missed it.
