Battery in tail
« on: August 12, 2020, 03:55:50 PM »
I want to mount the battery in the tail. when I had the battery out I hooked up to the end of new 3' extension leads and meter read 13.3 volts. when I plugged it all together and turned the key to the on position it was dead, no power to the dash lights, nothing.

what am I missing here

Verify that the cables are connected to the correct terminal polarity.

That doesn't tell me much. What is the voltage between the negative and positive battery terminals right now?

13.3 at battery terminals & 13.3 at end of extension leads , I hooked it up to bike with correct polarity
I'm putting it back to stock for the moment & taking a quick ride
going to try and beat my old record of 15 min that I had with old coils  112350

I assume you connected the new leads to the all of the original + and = battery leads?
