Thanks Phil, I got to thinking about how I thought the battery died. Actually it just kinda slowed down, then stopped all by itself about 60ft away. I dragged er back in with my retrevial boat. When I got home I charged the battery and put it back in. Nothin!! Just some clicks from the esc. I pulled the motor tonight and jumpered it directly to the battery, It works fine. So I pulled the mystery box off the bulkhead and discovered it had 4, philips head screws on the back, so I pulled it apart. The pictures tell all, its a whatchyamacallit!! LOL Anyhow I did a continuity test on it and it checked good. So now I'm thinking I might need a new esc, huh? Just where would I find an antique like that one? Or should it be updated? Thanks, Brian
