My 8n starter won’t engage, I can hear a single click from the solenoid but the Engine won’t crank. I just got done replacing the water pump and put everything back together. When I went to start it the engine was turning but it didn’t want to start. After cranking for a while I went to take the key out ( it’s been converted to 12v) and it kept trying to turn over. I didn’t want the battery to die so I crossed over two of the lines on the back of the ignition switch with pliers and it disengaged. I then tried to crank it again and the solenoid just clicked once but nothing happened. Kinda lost hear any help would be appreciated.
