Hello,
I recently got a Barcrest Golden Years with a MPU4 Mod4.
It starts up all fine, but if you try to get money out of it it says: Obstruction Alarm.
As this normally concerns the hopper, I replaced it with a completely new one.
But surprise, surprise it did not solve the problem.
I then took a look at the MPU itself.
There I could see corrosion by the battery all over the board (pictures included).
As I am new to this area, I hoped to get some help from you.
I did search in various boards, but did not find an instruction on how to fix this problem.
Should I simply buy a new MPU?
And if the MPU can be fixed, can the battery just let out, to avoid any corrosion in future? (I do not need any saved credits)
Thanks a lot in advance,
LaRie
