This is how to beef up the battery carrier
1 Remove the 3 screws on each side of the battery carrier, put screws in bag, remove the 2 aluminum plates, notice how the black plastic center post isolator go, then remove and store in the plastic bag.
2 Use Flitz polish to polish the aluminum plates to a mirror shine
3 Use alcohol then de oxit then progold on each of the gold contacts where the screws go in.
4 Loosen the center positive contact, it is a screw you just use pliers to twist it open, Polish with 2500 sandpaper then clean with alcohol, then deoxit then progold. pay attention to cleaning and progolding the underside of the screw where it contacts the PCB
5 Use a hot iron and soldering to beef up the contact between all the springs and the PCB base.
6 Put progold in all the screw holes before reinstalling the center screw
7 Firmly tighten the center screw using pliers on both sides of the battery carrier, careful not to strip them.
8 Clean the underside of the polished aluminum plates where they contact the PCB then use alcohol, then deoxit, then progold.
9 Make sure all the gold contacts in the Battery Carrier where they contact the aluminum plates are clean and progolded
10 Re install the black plastic positive contact isolators then the plates and tighten the 3 screws on each side firmly, careful not to strip them.
You are done with the battery carrier!
This is how to beef up the switch PCB plate
To access the contact PCB plate you will need to boil it inside a ziplock bag in hot water and use strap wrenches to open it.
1 Remove the PCB switch assembly.
2 Clean all the gunk from the tread using alcohol and Q-Tips, pay special attention to the shinny shoulder at the end of the treads
3 Polish the shoulder using Flitz to a mirror shine, then use alcohol, then deoxit then progold
4 Clean both sides of the PCB with alcohol to remove the gunk and grease from factory
4 Beef up the 2 spring contact with the PCB using a hot iron and solder.
5 Beef up as needed the contacts between the switch and the PCB, and the electrical connections of the switch
6 Clean with alcohol, then deoxit then progold the gold ring around the PCB and all parts that have electrical contact.
7 Re install the switch PCB and lube the Tailcap O-ring, tighten the tailcap
You are done!
