Check ovp relay fuse

I will do that, thanks.

Is this located in the main fuse box?

Thanks!

Its located behind the battery, you might have to take the cover off to get to it. If the cover is still on there. Also check the throttle linkage, gas pedal. Fuses. Check the basics

See -> overload protection relay also known as OVP - overvoltage protection relay in the link below.

A small door on top flips up providing access to blade fuses inside. There are usually 2 fuses, although earlier versions of this has only 1 fuse.

Thanks a lot! So if the fuse in this is blown, I will need to get a new one rather than replacing the fuse in it?

I will look for it tomorrow. Thanks!
