A couple months ago, my ignition switch started acting wonky. The entire bike would shut off while riding, the instrument cluster and lights dead. It would restart after a few minutes. This happened twice, then, no power with key in. I thought it might be the starter solenoid, I replaced that, no dice. I bypassed the ignition switch and put in a toggle switch, one wire to ground, three to positive. Everything was fine for about a month. Then, no power again. Test light across hot and ground lights up, but switch does not work. Replaced switch, started right up, ran for 5 minutes, died, and now the same thing. Any ideas would be greatly appreciated.
Have you blown a fuse & when you say the ignition switch is burning out, what does that mean? Are you seeing burn marks or what?
I would inspect as many connectors as possible & as much wiring as possible before installing a brand new switch.
And make sure the correct fuses are installed.
I am sort of waiting till new switch is installed and tests are run. I will ask what sort of rating (volts and amps) the switch is rated at. Keep in mind that if the battery and fuse are working correctly there should be power to the switch, but not out of the switch until either the toggle or key is turned to on.
