My 853H was running like a champ but had a leaky gear pump. It sat for about 10 months before I could get to it. I didn't start it at all during that time because I drained all the hydro fluid out of it so it wouldn't leak. Over the last few days , I pulled the pump and rebuilt it. After reinstalling the pump and putting in fresh hydro and a new battery in, I tried to start it, and the problems started. When I turn the key on, the ignition comes on and the display lights up, but when I turn it to start, nothing... No clicks or sounds of any kind. I tried bridging the solenoid and got the starter to engage, but I think I've made things worse. After trying to start it by bridging the starter a few times, the ignition went dead. Now, if I turn on the key on I get nothing. But, if I add a booster battery with the - on the frame and the + on the positive pole (B) on the solenoid, the ignition comes back on. I'm at a loss and now have 2 problems to chase. First, the original problem- why didn't the starter turn after I finished the original repair? Second- why is my ignition now dead without the addition of a booster pack? Any help or advice would be greatly appreciated.
