Not to be argumentative in any way.
Current is stupid, ya gotta get it going on the right path.
That said, one does not have to polarised a system often, or do it like a tune up or as things wear.
It does not cure a system of not charging today that worked fine yesterday.
You have a 50-50 chance it will charge correctly when replacing components.
The first thing you did after replacing components was polarise it.
If occasionally you ran into a new component that failed to operate and returned it to the vendor, the first thing they asked was did you polarise the system, you better say yes because if you said huh, or no, I didn't
pulverise it,
they said sorry no exchange/refund because you prolly damaged it.
and you better of had connected it properly because if you let out the magic
smoke
they can tell you had the cover off because of usually a paint mark or the burned points inside.
If you would like take some time to read up on it, and help yourself understand, please do.
During normal operation, a system does not need it done, or even year to year.
and it only takes one millisecond, just a very fast spark to accomplish it.
Another case of more is not better.
