My Aprilia Caponord ETV has started to burn its Delphi AMP 3-way connector fitted in place of the infamous brown connector. (My 1997 Cali has not got the same generator ooomph!).
I recall that the brown connector was common to Guzzis, Triumphs, etc. and gave the same bike-on-fire potential.
Any recommendations for a properly rated waterproof 3-way plug and socket? (The DELPHI 280 series rated at 14A per terminal was inadequate and started to overheat).
I don’t know if this would be any good

Maybe a starting point for your search
Thanks Brian.
I had already identified the AMP/Delphi (now Aptiv) as the most suitable and have taken care to get the correct connector pins. Now here is the rub, RSOnline and Farnell only have the connectors on massive reels (2200!) or available on back-order.
You have to be careful with the eBay kits and get the correct connector pins. You can easily fit lower current pins into the same housing in error.
I have used 3WayComp on eBay before and he has been generally reliable; so parts carefully selected and ordered.
Then a sudden brain-wave (the last of 2021). The melted connector plug replaced an Aprilia OEM “brown-plug” running to the regulator from the alternator. I fitted a much better MOSFET Regulator (Shindengen FH012A), so why not simply hard wire with heavy duty crimp? I already have a heavy duty ratchet crimp tool and good shrink sleeve connectors. I will look at the Regulator Plug placement and sort - hopefully today.
PS. If anyone is tempted to do a regulator upgrade then genuine Shindengen are superb. However, beware of cheap fleabay offers of counterfeits. This guy is good https://www.ebay.co.uk/itm/380704480069?_trksid=p11400.c100710.m5035&_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20170110123657%26meid%3D37daad915ca24027913a541459728d11%26pid%3D100710%26rk%3D2%26rkt%3D2%26mehot%3Dpp%26sd%3D292151609888&ul_noapp=true , but you can get used Regulators from breakers.

So much for brain-waves! The regulator fitted is actually an FH008EE with leads to a Honda Plug; which was replaced by a Delphi Weather-Pack. The FH012 and FH020 were physically too large for the frame fitment and a plug is essential for disassembly; should it ever be required.
Back to checking that I fit the highest current connector pins next time. 
PS: Now settled upon a sealed Delphi Metric-Pack 280 series (30A per pin connector rating).
Antonio at 3waycomp came up with the goods (Delphi Connectors) and I can thoroughly recommend him. His eBay Store is at https://www.ebay.co.uk/str/3waycomponents?_trksid=p2047675.m3561.l2563
I have no connection with 3waycomp other than as a satisfied customer.
I also splashed out on a delphi-specific crimp tool. The general purpose crimp anvils are not suitably sized or shaped.

Had a look on the shop and spotted what looks like one of the relays that is part of the fuel circuit on my Sport - lot cheaper

So will investigate further but may be a cheap fix for anyone who has water in the relay problem
