Battery Drain on Kart with LED lights, lights never on.

[Dfoster]

I'm a noob so go easy...

I recently added a new motor to my sons go kart. A Honda GX 340 clone 11HP with a 3 amp charging system and electric start.

Everything seems to work fine. Lights and electric start. The battery goes dead after one day of use, and not even using the lights.

I hooked a test light up to the negative side of the battery (with motor off) to the cable and the light is on, meaning I have a draw somewhere.

I remove the fuse to the lights and the test light goes off.

The LED lights are not on, but drawing power somewhere. I have a SPDT switch with an LED (only illuminated when the switch is on).

Both positive cables are wired to the positive side of the battery (2 for the lights; 1 from relay 1 from switch) There is a 40amp relay also.

The grounds all go to the motor.

Any ideas would be appreciated. Just trying to keep the battery charged for as long as possible, as it wont start the next morning.

This is the second motorcycle battery I have tried and it has to be in the wiring but I don't know enough about it to trace what's wrong.

Do either of those positives need to be somewhere else? (on the charging nut itself?)

I'm lost.

I'm just guessing here, but kill switches work by grounding out a positive wire....

Find the draw first. Just have to chase wires. Battery positive should go to switch for lights, then to the lights, ground is either the frame or the battery or the engine block. Ground is ground and all should be grounded.

What kind of LED lights are we talking about why do you have a relay? How many amps do they draw?

This is where pics come in handy for us.

Do you have the charging coil hooked up to the battery?

Ill go take some photos and post back in a few minutes. I'm certainly no electrical guy BUT there are 3 positives, one from the relay and the second from the switch, the third goes from the charging coil to the battery.

I'm thinking about when I hooked up fog lights as a kid to my car, one of the positive went to a 12V accessory, which only got power when you started the car. Since both positives are connected to the battery, is that second positive drawing power thinking the car (go kart) is running?

I used a relay as I thought it would be easier on the charging system, I'm probably totally wrong on that. I also purchased a harness from Amazon that may not work with a single battery setup.

Here is a stock image of the charging system of the engine.

Here is my battery, and the charging system. I know these are crappy photos but hoping you can see what I did.

In the first photo I removed the one power wire to see if the lights would work without it. They didn't.

In the last photo there are several wires that come from the motor. I have no clue what they are for, I assume a kill switch and power? The large red wire that comes off the charging bolt and runs to the battery, I think my charging systems is connected. The negative comes off the battery and connects to the motor/ground.
