PowerStation model PSX3 has both tire inflator and jump starter functions. It also has a work light. The inflator had been working fine, but now the push button switch has no effect. Seems as if an electrical connection has been broken. The work light functions perfectly, so there is power available. Inspection of the interior wiring didn’t reveal anything obvious.
david barkman it sounds like a bad switch (mechanical failure). If you can disassemble it, check the switch and you could always try to replace it. We would need to see what it all looks like in order to give you more details. You can always post some pictures so that we can possibly provide you with a more precise answer.
