Hello all
I have a roc-132-4 type ccd4-148B (pepsi vending machine) - Looking for some help
Lights work
Figuration works
Shows selection avail when filled
I put in coin and it they fall directly to coin return
It is a MARS model (looks like 5000? Cant clearly see but looking at pictures) it appears tobe. Serial is 051238
I'm not sure where to start troubleshooting
The three switches which I presume enable the coin dump (5/10/25) are in the down position. When toggled and have coins in the MARS holder I would expect them to return.
this is not the case. I feel the MARS unit is not getting power but not sure where to troubleshoot first.
Does anyone have a thought or schematic for the pins on the MARS unit or the schematic from the ccd to the MAR unit? I could verify power to the MARS itself.

Thank you - Peter 551-427-1178
 
I verified 120V power to the MARS unit (pins 1 and 2) . So the changer is getting power.
Is there an upgrade or replacement part for the MARS I've seen the conico 9300 but not sure.
thank you
 
So to summarize:
You have loaded the machine with product.
The product sensors (product available) work.
Did you program the price per product into the unit?
 
Can you post some pictures of the unit and its model number plaque please?
 
I believe I have isolated the problem to a bad vend relay.
The relay is labeled L29A and looks From the manual it is labelled as a V-13410.
Anybody have a source for a new relay? thank you

One available. Another guy who had 9 used ones just sold out. They look kind of rare.
