Hello all,
bit of a desperate plea for help I'm afraid.
I've been working on a range extender for my leaf - The packs are fully built and balance charging as we speak.
This morning I have spliced two high voltage cables to the HV cable between the battery and inverter (No extra battery anywhere near the car yet) this seemed to work fine and when the car was turned on I got a reading of 360volts between the ends of these two cables as expected.
I was then trying to work out how to get the RLY P (yellow cable on the data connector) to control a gigavac relay that will eventually be used to turn the extra pack on and off in sync with the main pack relays.
It was at this point that I've done something obviously rather stupid as the car now will not start.
I connected the yellow cable (again a spliced connection) to the gigavac relay in the boot, and from the relay on to what I assumed would be ground (i.e. the chassis). clearly this is the wrong thing to do and I can now see that there appears to be a RLY P ground wire.
On turning the car on it seems to have less charge than it did earlier in the day by about 10% and will only respond as though started up without the brake pedal depressed. It does not accept charge.
I've read a few forum pages and the common theme seems to be a blown pre-charge resistor - I think???
Will what I have done above have caused the same? can you think of anything else that I can check to see what damage I've done?
Best Wishes and with much gratitude,
Andrew
