Honda Prelude Main Relay Repair

Believe it or not, this main relay cause
 the ECU throw Code 15 "Ignition Output Signal" and can't start.
Luckily i heard weird sound while turn the key into "On" position.
I hold the main relay box and feel the relay was crazy.
Opened it and discovered some water in the box.
Wiped the water, the engine started easily and no more ECU code.

I decided to rebuild it to last  longer.
Desoldered the pin.
Dirty with soil.
The circled things need to be cleaned with 1000 grade sand paper.
Solder them back.

Good Luck!
