Hi i went on the site: http://www.nyx.net/~smanley/hondadrlfix/index.html
but i dont know what they mean by "What you need to watch for are cracks or any surface that does not look smooth." What do you exactly need to solder. and how do you know which one to solder. i opened it up but i dont know what to solder.

Above link shows bad solder joints on a Main Fuel Relay (MFR). Your's should be similar. Cracks are diifficult to identify w/o a powerful magnifying glass. On MFR I reflowed all the joints to be certain.

The relays and step down resistors generate substantial head 2-3 watts on MFR. This results in spot temps as high as 150F on stepdown resistors and 100F on relay. Combined heat causes stress on solder joints and they eventually crack and fail.

If you have a wiring diagram of the relay, you may be able to identify the relay leads and resistor leads that will get very hot.

good luck
