I picked up a K250-1 on auction and brought it home. It's bare metal, no tuck and roll, etc. Are there kits or replacements? The plastic sleeve on the power switch had broken off. Thanks to the community member who suggested on someone else's post that you can use zip ties to secure the switch to the mounting bracket. Works! My question is, without a suitable cab to test out this unit, how can I test this K250-1? Thanks
