Fuse keep on blowing in battery. Powacycle Salisbury.

[Hazel2705]

Cycling home from work and suddenly lost power and there were no lights on the battery. Got a new fuse and battery worked fine again. Put the battery back in the bike this morning and turned it on and all lights flicked off so I assume the fuse has blown again. Any ideas what this might be? Something on the bike is blowing the battery fuse but I have no idea where to start. Only had the bike since Sept!

You do not say if you bought the bike new or second hand . Assuming it is second hand , have a look round the bike for obvious signs of damage to the wiring. What were conditions like when the bike failed, climbing a hill/ Heavy rain? What is your level of technical ability? Do you have a multimeter, and do you know how to use it? Take the fuse out again and check it, you must not assume. When you put the battery back on the bike and switched it on, it is strange that the fuse should blow at that point, because unless the bike is capable of powering up from a standing start, and the throttle was open, the motor is not in circuit. All that should be connected at that point is the controller, and the battery-to-controller wiring . Of course it is possible that the fuse is ok, but the battery connections are dirty where it connects to the bike. We need a lot more info . Please answer all my questions.

Fuses blow for a reason! Which bike is it Hazel? Either the replacement fuse was the wrong size, or more likely, there is a fault in the bike that blows the fuse in the battery.

Perhaps, given the weather recently, you have ridden through some deep puddles?

It was new when bought in September.

Sent the husband out to the garage to have a look and it's the small metal bar with the prongs that go into the battery has snapped in half and there is corrosion around the wires connected to the prong bar. I'm going to phone powacycle on Tuesday and see if I can get a new prong bar then husband said he will solder it.

The fuse hasn't blown. The battery lights up when it's not connected to the bike but when we put it back in place it won't work.

It's been pretty wet recently so that might why there is corrosion? At least we've found the problem now.

That will be the problem then Hazel, shorting across the terminals. Those battery connector blades on the battery platform of the Salisbury are thinner than many and can give connection problems.
