My L2900 has an electrical problem. No lights when I turn on the key. No start, nothing. I have 12 volts at the switch battery post. Starter has 12 volts, the slow burn fuse (40A) is good. All power disappears at the switch battery post when turned on. I have the schematic on the electrical switch. I can't see anywhere that the power, once at the switch should "disappear" with turning the key. Bought a new switch but that did not accomplish anything other than reducing my checking account. Stumped in Kansas. Forgot to mention that the battery is good as is the ground.
