82/70 ss chassis

[buffalojim]

I HAVE A 82/70 SS CHASSIS THAT KEEPS ON BLOWING THE F1 FUSE WHEN YOU TRY TO CYCLE THE MACH I HAVE CHECKED FOR WIRES GROUNDING OUT THE PLUGS ARE FINE.I AM STUMPED I HOPE SOMEONE HAS AN IDEA.

F1 protects the T1 transformer....

Good luck.

Wrong fuse?(had that once...).

Will the BE run if you reset your chassis?
If so, the first 24 V circuit that will be used after you cycle is the sweep relay.

Good luck,

Re: 82/70 ss chassis

We've had a couple like that already... so far, every one I've sent to Stahl's (got sick of fiddling with them myself) came back with the diagnosis of a bad transformer.

The only other thing I know of that can cause the T1 transformer fuse to overload (other than bridged/burned-out windings) is a dead short in the T1 secondary wiring... it'll cause the primary windings to overload.

Re: 82/70 ss chassis

i did replace the t1 transformer and it is good but the f1 fuse still blows when i try to cycle the mach. the backend moter stays runing and the pit lite is on.there is no 1st and 2nd ball lite and i have the wright fuse in it.i still have to check the sweep relay. this has been a pane in the butt.

Put a new sweep relay in there !!

<font size="2" face="Verdana, Helvetica, sans-serif">Lampie raises a GOOD point there !

The fuse should be a SLOW BLOW ( 3 AMP from memory on 110 Volts )

A Standard or a Fast Blow fuse will often Pop immediately as the initial current load is higher than the fuses' blowing current rating ( Usually 25% higher than the Stated rating on the fuse ).

Slow Blow fuses will have a T ( Time Lag ) designation on them

Fast Blow fuses will have a F ( Fast ) designation on them

Standard fuses should have nothing other than Rated Voltage &amp; Current on them .

Re: 82/70 ss chassis

i put a new 3 amp slo blow in it and it still blew it as soon as i hit the cycle button.we had a new t1 trans and i put it in but i still blew the fuse.the backend moter stays on. WHAT A PANE IN THE ASS.

Re: 82/70 ss chassis

Under neath the T1 transformer there are three diodes. Change the outside 2. This should take care of the problem. The reason I change both is because its difficult to tell which is the bad one and at less than $1.50 its easier to replace both.

Re: 82/70 ss chassis

thank you the power diodes were it. now it is working fine thanks agian for all the help
