i just bought a brand new motorguide 70lbs thrust trolling motor hooked it up. its not the first trolling motor ive hooked up so i know that the battery cables are wired right and so is the plug in the boat etc... however the trolling motor only turns for about 2 seconds and then dies completely and it sounds as if there is a sizzling sound in the lower unit any ideas? i have a tournament in 2 weeks and im afraid if i send it back then it will take to long to get the new one back to me. i have a feeling it cant be fixed and it is just a defective product that motorguide produced however if anyone has encountered a problem like this and was able to shed some light on my situation so i dont have to bring it back that would be  appreciated.

take it back to the place you bought it.

Rather than telling us you KNOW the battery cables and plug is hooked up right, why not explain to us HOW you know that?

Get out a voltmeter, measure the voltage going to TM and is the polarity correct.

Otherwise you'll have to take it back to where you got it.

I just went through 3 motor guide varimax tm's, then I got tired of the bull and got a minn kota, and I love it.

update. fixed it!!!! yay lol i was ticked off taking it off the boat stepped on the cord that goes to the plug and vrrooooooom it took off. so i sliced the cord and the negative wire had a slice in it it must have been from the manufacture plant because the rubber sleeve had not been tampered with but the ground wire only had about 2 strands holding it together spliced it together crimped it and now it works like brand new. saved me 70 bucks in shipping. i find it wierd that during the manufacturing process something so stupid could happen. dont they test them before they package them up?
