Discussion:
Unit will not power up.

Hello all.
I have a 7HBW23 that will not power up after someone hit the battery connector and bent it back when traveling. Remarkably the connector did not suffer any damage but the unit dies right there and would not power back on.
I checked all power to and through the battery connector.
The traction control card is blinking slowly to let me know it has power but I have no response from the keypad on the tiller handle when trying to enter the operator code....no green LED conformations. Borrowed a control head from another identical unit on site to get this one moved and out of the way. Unit ran fine with a different control head. Tried switching the keypads but this did not help with the original control head. I'm assuming they are not telling me that the control head was also somehow impacted although I can not see any real damage. Is it possible the Etac card failed from impact? Has anyone seen that happen?
Thank you.

Bad tiller card (inside control head) has small transformers soldered on that fall off from strong impact. You probably need a new tiller control card.

Dreamt I was fixing a machine, then came the paperwork and it turned into a nightmare.
pull the cover off next to the diagnostic port there is a small round twist lock fuse. make sure it didn't pop out.

Start there.
