Default Corrosion on point motors

Hi all,

Iíve been having trouble with my Gaugemaster PM1 point motors and have noticed a build up of corrosion around where I soldered the wires on. What is causing this and is there a way of reducing it? I was thinking about covering the terminals with dielectric grease, would this help?

Cheers!

Exactly how did you do the soldering.? Did you use a separate flux, if so, what was it?

I think the flux is the problem as it isn't really meant for use on electrical work, it's a plumbers flux. Plumbers usually flush out the pipework after soldering to get rid of any residue but you can't wash it off wiring.

There are proper fluxes available for electrical work that don't cause corrosion but if you use a solder that has an inbuilt flux, such as that which you have used, you don't usually need additional flux, though it can be helpful in some cases.

i use a plumbers flux, but i only wipe the wire with it using a cotton bud or cocktail stick, the problem is using too much and can't burn off,

Tin the wires and tin the tags if not already done. Extra flux not necessary.
