So I found out quite a few things this weekend. First, my little 6.7 inch ADC K99-4007 does not like hills at all. There are a few hills around that I purposefully avoid, but today my dad wanted me to try one. The motor cried the whole way up and barely maintained 10 MPH. It didn't help that I had no running start, and the transmission computer decided to shift down to first, essentially making me lose what power I had. It did go up the hill, but the motor got quite warm, so I half to avoid these hills and make a forced air cooling system. I was probably pulling over 250 AMPs at the motor, which it did not like.
Here's a summary of changes I need to make and what I need to do before Thanksgiving:
- Bolt down all the batteries
- Make better cables and get lugs for the controller and motor
- Create a forced air cooling system for the motor
- Beef up the motor mount and bolt it down
- Complete control box
- Mount breaker into cabin
- Finish Vacuum Brakes and PVC tank
One of my chargers also died today, I think one of the internal relays gave out. It makes thing ticking sound and then displays "Check Error" and shuts off. So I will buy another bunch of chargers on eBay.
I have this Tuesday off from classes so I am going to make my small part shopping list and get as many things down as possible.
I would like to be able to drive this to my cousins house for Thanksgiving, which is 12 miles away, and then plug it into charge when I arrive.
