I just bought a CS-80C vending machine, I bought a manual for it and have currently started to clean it up, replaced the wireharness, and the two main light bulbs. However, I have no clue how to access the flourescent bulb and ballast/starter for the main "Drink Coca Cola" sign. Any ideas how to replace? also, the sign that's in the machine is a newer sign, and I will want to replace it for a sign more period for the machine. How do you remove and replace this sign? Thanks for any help!
