Good morning,
I've been having all of sudden failing left flipper on my LOTR, so I took a look and investigated further. Turns out the fuse was blown, but... I changed it and since then it has blown twice.
Before I blow any more fuse, I did further testing
- I checked the flyback diode, it was OK
- I used my current probe to check on amp during test, as it turns out:
- I have a current peak slightly above 4A on the left flipper
- I do not have this current peak on the right flipper
Kind of explain why my fuse kept blowing.
Now that does not explain why I have a higher current peak, is this typical of a transistor starting to go bad ?
On the questions now:
- I have the high power coils, would that explain the higher current peak ? If so, why only on the left flipper ?
- I looked at the schematics, could not find the reference to the flipper transistors, could someone give me a pointer ?
- Should I simply replace my 3A fuse with a 4A ? I assume it's not recommended...
Thanks
