Editing AFM (section)

=Silvertop RB20 AFM=

OK, so I was having a problem with my RB20 breaking down at around 2000 RPM.  Replaced the plug on the loom as I suspected this was the problem BECAUSE when I lifted the plug (while connected) it seemed to contact better and I could hear a difference in the running of the engine and when driven was all OK until I hit another patch of bumpy road which I then thought would rattle the plug and so on.... So once plug replaced, it made a difference. However this only lasted a few kms until it broke down again.

I figured there had to be something i could do instead of getting another AFM which may not fix the problem.

Turns out it is as simple as the solder on the contacts inside the AFM not connecting as well as it used to, so here is the procedure for what I did and haven't had a problem since.

NO GUARANTEE THIS WILL FIX ''YOUR'' ISSUE, BUT IT WORKED FOR ME...


Tools needed:

*Screw driver (to undo clamps)
*Razor blade or Stanley knife
*Soldering iron
*Solder
*Sikaflex or something similar


Step 1: Remove AFM, undo the 2 clamps on either end of the AFM and unplug the connector plug.

Step 2: Using your choice of blade, CAREFULLY cut away the silicone sealant around the top of the AFM. Cut deep down the sides as it is really in there. And then gently pry the cover off to expose the copper plate. Use your soldering iron and melt the dab of solder which is holding the plate down and remove the plate

This is what you will see

Step 3: Simply add solder to the contacts already soldered... melt it down a little bit and re-apply solder, careful not to put too much heat into the rest of the circuitry or join them together. Let cool and re-attach copper plate.

Clean up remaining silicone, re-fit top of AFM, and apply sikaflex neatly and to whatever way you see most effective. Re-fit AFM to vehicle, reconnect plug and road test.


Thanks to some random out cruising who said he had the same problem with his 32 and told me about it.
