I have a B4630, GST, bought it used, about 2 yrs ago. Ran fine. Yesterday went to dig hole for friend, everything went great. When leaving, they wanted to talk to me, and since I'm getting hard of hearing, I had to shut the machine down. Was running perfect until then. Battery is fine, but no dash lights come on, won't turn over, and don't get any click from switch when key is turned. Does anyone have any Ideas??? Being retired and on fixed income, I'd rather try and fix it myself, if possible! HELP please!!! Thanks
