I recently bought an 12v battery jumper pack. I wanted to make sure I could easily access the 12v battery before actually needing to. The space between the two terminals are so cramped that I can't get both cables to fully clamp around the terminal connectors. Would it be okay to connect it to the bolts/nuts as shown in the image instead of fully around the terminal connectors? Has anyone had to do this before and been able to jump start their prius C?
Why not just use the jump point under the hood; rather than rip out the access panel under the seat???
The cables are very short. I couldn't reach the spot that was recommended to connect the negative cable clamp to.
The car has a negative-ground electrical system, so pretty much any unpainted metal you can reach with the clamp will do the trick. I've never tried to jump a Prius c, but I also can't remember in any car ever having to look very hard for a place to clamp the ground.
^That or preemptively install a short ground jump wire and tuck it away. That's what I did for my old 2012 Prius C.
Early production c's didn't have a jump point; was a real design fail, considering the battery location. @pasta4breakfast doesn't disclose his year though,. If there's no under-hood jump point, maybe just wire in some sort of quick-connect??
I carry a 2 foot #6 home made jumper with good size alligator clips in our Rav4 hybrid to avoid the "easy" ecm frame ground which is known to blow the ecm on occasion. However it has seen more use when providing a jump to big pickup trucks.
clamping the nuts is fine, even though there's not as much contact area, it can still work. Wiggle it around if it doesn't work right away. Look in the owners manual, it may show a clamp point in the underhood fuse box. One of the big problems with a 2nd gen is if you stash your jumper cables in the trunk by the spare you can't get at them when the battery is dead, because the trunk only opens electrically. So I stash my cables under one of the front seats, because you can get at them with the mechanical key to open the door. Just another simple thing overlooked by the genius Japan engineers. They were so focused on building the most technologically advanced vehicle of it's time, they missed some of the small simple things.
As I recall; it was a very skinny jump point - those clamps pictured above won't clip-on. My solution was two quality alligator clips, then clip onto the alligator clips. It wasn't pretty, but it works. No getting on your knees and fighting the lower seat panel cover. Another idea is to run a couple of short jumper wires from the battery and drill a couple of holes in the plastic cover to put a bolt through. You can just clip onto the protruding bolt heads to jump. The bolts will need to be far enough apart so that there's no accidental bridging of the two points. As I recall; that access panel was a bit of a pain to remove; with my tool box next to me. I can only imagine the pain, in a parking lot or side of the road w/o tools. YMMV
