So I have a 2008 Tomberline Emerge E4 I just got it running after sending the controller to FSIP to be rebuilt. It ran on and off for a few minutes at a time however I can hear the main large contactor turning on and off. When I press the accelerator down after the contactor turns on I hear and can see sparks from the main Negitave battery post for pack voltage spark. Im scared to ruin any thing and can't for the life of me figure it out. By the way the connection on the battery post is tight Aswell as the connection to the controller in this case I have a GE 403TB1 controller. When it did run it was not running full speed at 20 to 25 mph and rather maxed out at around 11 mph. The things replace are new speed sensor, newer main contactor, new pedal assembly, new forward/reverse, motor, hall effect sensor, key switch, and new batteries 8 6 volt crown batteries. When we replaced the batteries I replaced the cables aswell however the main cables for pack voltage are old and the cables to the controller are old. Any input is much appreciated thank you.
