Rectifier Replacement

Lately, I had three bulbs blow on me in a time span of two months.
On an extreme tour, i had my meters reset a couple of times at high rpms. At once, it switched off and on when I was on the fast lane. So uncool

Something must be amiss right?

Though there may be many diagnosis of the failing electricity, it can be time consuming and expensive to solve. There are usually four components to electric problems.Battery, stator, rectifier and wiring( to some there may be others like connectors and ground). Since bulbs are blowing(probabbly due to a spike of voltage) I pointed it to the rectifier. Rectifier and stator problems sometimes only happen occasionally. Although the rectifier looks like a solid state unit that will not fail.. well it  does.

My own research shows that ybr125 rectifier looks, mounts and connects exactly like the ybr250.

Here are pics. And the bike has been working fine since.. I will update if the problems will come up again..


Right is new
