"Last week after I arrived hom

"Last week after I arrived home after a full day fishing I went to trim my motor up and I had no power, the crank battery was dead. I put the battery on the charger over night and the next morning the battery was still dead. I replaced the battery and a few days later the new battery was dead. I then disconnected all wires and motor cables and charged the battery to a full charge, but when I go to reconnect the motor cables to the battery I'm getting a lot of sparking like something is drawing power causing the battery to draw down when nothing is on. Anybody no what could be causing this to happen?"
 
Do you have a main battery swi

Do you have a main battery switch? If not you should. The only accessory that should bypass the switch and be live to its own switch is the bilge pump. Its probable you have a short somewhere. A bad wire with the insulation rubbed away and touching ground. Or something your not thinking about has been left on. A battery switch will prevent accidental dead batteries and possible electrical fires.
 
Yes I have a main power switch

Yes I have a main power switch. I disconnected all wires to crank battery except for cables to motor and battery so the short would only be there but they look ok. Something on the motor must be pulling power from the battery when hooked up.
 
Lyle disconect the harness plu

Lyle disconect the harness plug (main wiring loom plug) and then check if the leads still spark when conected and disconected. This will isolate where to look next
 
"I reconnected the cables to t

"I reconnected the cables to the battery, removed cowling and I could hear the slightest crackling noise coming from the fuel pump area. After a couple minutes it seemed to get loader so I immediately disconnected the cables. Do you have any idea were the noise is coming from."
 
"I can't answer your quest

"I can't answer your question, but please be careful with sparks and battery charging. Charging generates hydrogen gas, which can be ignited by sparks, and cause the battery to explode! That is why you should always turn off the charger before disconnecting."
 
Lyle start looking at the wiri

Lyle start looking at the wiring around that area and see if any wires have worn through the insulation...dont use it until the problem is sorted out as you dont want a fire. If you cant positively identify the problem take it into a dealer
 
Try conecting it breifly with

Try conecting it breifly with the cowling off at night time in the dark. You may see the where it is shorting better and pin it down to the wires in question.
