I have recently installed a quickshifter controller on my motorcycle. This device consists of a small electronic controller unit, a sensor connected to it and an ignition cutoff cable also connected to it. It seems that there are plenty of places to install this control unit but I decided to keep it close to the sensor and cutoff cables.
So (and since the bike has limited space under it's fairings) I ended up placing the control unit on the bike side right at the end of the fairing. This helps me diagnose issues through a small led on the device and also keeps it a little further away from high cylinder temperatures though still it receives quite some heat.
The issue here is that it seems a little exposed to rain and washing waters. Since the small (sensor) connector on the device cannot be modified and is not waterproofed by design I would like to know if there is a way waterproofing it.
Solutions I have thought include special contacts waterproofing grease (which will probably get softened by temperatures and drip off), balloons (which I know from experience quickly gets dried up in heat and shatters), condoms (similar behavior) some type of plasticine type rubber in which I could enclose the connector, heat shrinking sleeve to seal on the connector and maybe a simple rubber cover.
Are there any other solutions and/or someone knows of a heat resistant waterproofing grease?
