Accelerator motor issue on gsx

[Farnboroughbowl]

Hi guy`s ive just changed a ball accelerator motor after it stoped working and now it seems to be running all the time as soon as i start up a machine. its not stoping after it should it just runs and runs untill i trip all power to machine then put it back on again and it stops. so i have to turn the machine off and on after every customer. Any ideas why this could be happening all the wires seem ok?

cheers

The relay for the accelerator may be stuck closed. When the other motor went, it could have arced bad enough to weld the contacts together. The location of that relay depends on your electrical box version. There willl be an identifying mark on or near it on the board. "ACC" i think.
You can see if it's stuck by looking at the little black manual button or lever when the power is applied to see if it moves. Might smack it with a screwdriver as well to see if it'll release, but you'll still have to replace it if it's stuck closed.

Hi Ted im using nexgens the newer ones ill have a look see if i can find it thanks for the advise I did find the 6 motor relays but I belive these are for the table distributar and sweep

I dont seem to be able to locate a relay for the ball accelerator any help would be awsome

The accelerator plugs into P26 on the R side. Since it's a NextGen, it's not the traditional relay, it's a triac. trace to J26 on the power board. You're likely to have the triac shorted, which means replacing it if you want. It looks like a big transistor laying on it's back, and should show signs of heat on it, or the solder connections. they are controlled by the white 6 pin optical controller chips near them. they can be bad, but it's usually the triac. Google the part number on the triac to find replacements. the ones at Radio Shack probably work. I thing they are rated at 10amps.
I'd have to look at one to recall exactly where it is and further advise you.

I order the triacs from www.mouser.com
They are very affordable there.

ive just replaced it as it did look damaged but it is still doing the same problem.

[Farnboroughbowl]

could it be any other chips on the board?

Ok guys I need some help I recently changed a ball accelerator motor after it coded BA and wouldn't start back up. When I put the new motor on it ran fine for about 20 minutes then coded BA. So I switched the NexGen out with the lanes beside it and the problem didn't follow. I ordered a new wiring for it (the p26 wire that comes out to three black wires and one yellow/green). It again ran for about 20 mins and then code BA. I don't know what else to change.

Try changing the functions cable out, the little 2 pin molex plug labeled "AS" i believe is what gives the nexgen the thermal overload signal. These drum motors and internally thermal protected, its a tedious job running the functions cable , due to so many things plugging into it.

Each lane has an accelerator power cable. We've had issues if we use the even lane cable but never if we use the odd lane cable.
