Tech folks and Baywatch owners, I could use some help. Here's the journey so far:
I've noticed that my Baywatch gets a little sluggish after about 30 minutes of play. By the end of a game, pops have less pop, the side kicker sometimes doesn't launch the ball all the way around the orbit and the flippers have a hard time getting the ball up the ramps. I opened the backbox to investigate and noticed the two fans mounted at the vent holes the backbox. If they're not working, the issue might be overheating components!
I did a test game with the backbox door open and during play and they only spun when the pops were active. The smaller fan would give a few spins but the larger one would only just nudge a little bit with each pop. Next, I did a coil test and discovered that the fans are attached to Coil 15 - a port that's listed as "Unused" but also activates the after-market shaker motor, which is attached to the pop switches. There's no mention of fans or their wiring anywhere in the manual or schematics.
So my questions are:
1. Did Baywatch initially come with two fans or were they added in later? Maybe they were part of the shaker motor kit for some reason?
2. If you have a Baywatch with a fan (or two) when are they supposed to spin?
3. If the fans are, in fact, factory standard, how should they be wired to the CPU or the PPB?
Thanks in advance!
