Double Jackpot 300

[Randy0777]

This is what happends when I power it up.
The reels do a slow spin...Then it says loading the game... the reels spin normal...  the insert coin comes up on the disply for a sec. ,then the lamp comm error comes up.
Picture 23 shows the back of the light wheel where the ribbon cable and a three prong conn. is,but nothing is on it  The other end goes to the board in the top(pic 29) which also has a three prong conn. with nothing on it.
Also in pic 97 the conn in the bottom right was not connected and when I looked in the manual it said that connection was for treasure tunnel. But,it will fit on the two conn. to the right also ???

I installed the the wiring for the wheel light and was able to get rid of the "lamp comm " error...now I just had the insert coin . When I would insert coin it would give a error "coin in pulse error"    Took the optics apart and cleaned everthing...same error. After talking to Ben ( like the 12th time  ) I pulled the main boards out and switched chips then retried in the games. The Double Jackpot is working great now  ... BUT, the 150 is getting a coin pulse error  . By now its 3am and to late to call Ben  But here is my question?

The 150 would not recoginze when I inerted a coin. The 300 would give me a pulse error. Switched boards(and game chips) and the 300 worked,the 150 now gives me a pulse error. So the board has to see the coin,right?
