Hi
Yes check big one the small one I think is soldered to the board not 100% sure about that one on testing as getting a spike then meter reads zero

I’ve had the same thing happen with mine, usually switch off & switch back on does the trick, tbh I think my motors are close to the boards limits, it is quite a heavy Tiger 1 lol

Silly question are the radio batteries good and is the radio properly calibrated? Has the tank been run a bit lately or sitting for a while.....

Does the board light up when powered up or no action at all?

Hi

It's not run for a while as other projects on going cleared all dust out with compressed air (no moisture I have filter on compressor) and the board does nothing no light no sound.

If nothing comes on It will be the small 2amp SMD fuse that's blown, it is removable with I very small flat head screwdriver, you should be able to get some more from Ian at rctank electronics. Hope that helps dude

Before you use screwdrivers and solder irons, please remove the battery, use a multimeter (use ohm meter): measure resistance on both ends of the fuse. It should be zero Ohms if the fuse is intact. If the resistance is infinite than the fuse is broken. In that case follow the advice from spongehoobtank82. But I think you already did. Does the led /light on the receiver burn or does the board receiving power (multimeter) ?Are the tracks blocked (grass between the tracks)? Or try this: disconnect the the multi-coloured turret/gun/machine-gun connector and. see what happens than (maybe there is a short in that part of the tank causing a faulty board.
