Sammy Aladdin A-Type - "HP" Error
Hey guys!
First off, awesome site! Got bit by the Pachislo bug after being given a Sammy Gamera (Red). I'm a regular posted over at the KLOV/VAPS and Arcadecontrols forums, and a seasoned veteran with arcade hardware and electronics in general.
However, this one has me stumped.
Got an Aladdin A-Type today, seems to work, but whenever the unit goes to pay out, I get "HP" on the LED Animation Display.
Full reset clears the error, but it'll never pay out.
Hopper dump switch dumps the hopper.
One thing I noticed is that when the hopper kicks the motor over to send coins, it appears to only turn about half as far as it should before giving the error. By hand, the hopper spins freely (Well, as freely as it can with heavy gearing in the driveline).
Cleaning the hopper and two opto-interrupts in the bottom of the hopper did nothing. I verified my hoppers work in my known-working Gamera.
Also switched power supply boards from my Animal Kingdom to Aladdin, no change.
The blue button near the coin dump key (I don't know the term for this. Reset?) will make the hopper motor do the same half-step. If you press it rapidly, you can get the machine to spit coins irregularly.
Any ideas?
