Chassis problems

[8270king]

1. All functions ok - except the chassis will not cycle......all C-2 wires traced and connections ok.

2. No table or sweep run unless you manually hold up the contactors.

Replaced a varisitor on the heat sink assy...... and it went up in smoke.....original varisitor was ok.....put back on.....the ones from AMF are not as large and wont to the job.

Re: Chassis problems

im sure you've checked the obvious three fuses. jump the back of them with a wire to make sure. also ive seen a stubborn M relay socket cause this, jiggle it in its socket, see if you can get some sputtering out of it

Re: Chassis problems

Jerry,Can you run the sweep with the SA cam lever? Can you run the table with the TA1 cam lever ? If you can not, I would look for a problem between the T1 secondary and the sweep and table contactor coils . Also , check pin 11b on the C2A block , as this is the power line that runs from the T1 to the sweep and table switches on the rear control box.

Re: Chassis problems

Chassis 1.....SS chassis....the sweep will run off the sa and will complete the cycle....I will check out the Inst. circuit today......should I just check cont. to to ground?

Re: Chassis problems

What kind of scoring do you have? If it is AMF Accu Score, it could be a bad lane A board.

Re: Chassis problems

JERRY,
was the c1 block changed? if it was,there are two thin green wires at the bottom corner row 1 and 2 right next to each other! one goes to the c2a plug and it should be on the 2nd row.
the other green one goes straight to ground! [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img]
try switching them around. I promise nothing will start smoking! [img]/content/btubb/images/%%GRAEMLIN_URL%%/wink.gif[/img]

<font size="2" face="Verdana, Helvetica, sans-serif">it's no secret,just pop out all the terminals then put them in the new block! :p usually takes about 15-20 minutes! [img]/content/btubb/images/%%GRAEMLIN_URL%%/wink.gif[/img]
