Power Loss?

Just working out the bugs...

I have had the boat running great except for a few power issues. I am experiencing power loss issues every so often, especially after coming out of a high speed turn. I will make the turn, and if I shut the throttle down to line up for another run, it will lose power for several seconds. The motor is getting current and I have full radio control, but power is very low and the prop will just barely spin...similar to when the batteries are close to discharged. One time it took me shutting off the power to the receiver to "reset" other times just waiting a few seconds it is was fine again. I inspected the boat and found no apparent esc issues (no beeping alarms as indicated if the Jetti gets overloaded), Motor is slightly warm, electrical parts are cool to the touch, wiring appears to be o.k.

After a closer look at home, I did find a possible connector issue. I'm using Cen/Tamiya type connectors and there was a female positive line connector post on my Y harness that was expanded. (I pulled this one out to re-crimp the wire connection and re-installed during constuction...my fault!) I gently brought it back into shape and have not yet tried the boat. Didn't think this would cause such a drop, but maybe. I am also wondering if this could be a connection problem at a solder joint? I am fairly new to FE so this may be a simple fix. Thanks (again and again!) ----Rob

The connectors are your problem. Change to a better connector - a gold bullet (see the options on www.OffshoreElectrics.com), or a Deans. It might cost a few dollars to change things over, but it is WELL WORTH the peace of mind.

First things first do what Andy suggests and replace those Tamiya connectors with quality bullet or deans connectors. Secondly check the brushes and springs. If the springs are not strong enough the centrifugal force of the boat going into the turns may pull the brush out slightly and it could take a while for the springs to push them back in it's proper spot.

another definition for the tamiya connectors is; fusible link! they are only rated for 15amps when new... as they age oxide builds up on the pins and resistance goes up further degrading their low amp rating. strongly advise that you replace them before they melt(and possibly short out).
