Radiator death by corrosion AAARRGH

Hi I have a K6 DL 1000, I was recently out on a day ride and on the way home discovered a slow coolant leak from what appeared to be the front face of the radiator, I figured a rock or stone since i had'nt the good sense to install a rad-guard when i bought the bike, needless to say I took it very easy the rest of the way home and monitored the coolant level. When I pulled the radiator out of the bike I noticed serious corrosion on the hose
tails and when I took it to a specialist I was informed to my horror that it was shagged, corroded out from the inside. The specialist said it was either electrolisis from stray electrical current or a mix of old and new coolant had been used. The previous owner of the bike had installed some led's in the front of the bike and the wires were exposed (the plastic wire cover was worn through and the copper was exposed) where they were trapped between cowling parts - I have since removed the led's and their wiring. It is difficult to determine if the damage was caused by coolant contamination and since I have now installed a replacement radiator with fresh coolant thats water under the bridge now anyway but the electrolosis possibility still has me worried. Has anyone heard of this happening before? Can anyone advise me of a good way to test for stray current in the bike frame or radiator?I do have a multi-metre. Any suggestions or advice would be appreciated. Sorry for the long winded explanation.

Was there only a single wire to the LED? It could be the lights had a hot wire and the body was used for ground. Using the radiator for ground would cause such a problem.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

I test the corrosion inhibitor life in the coolant with a multimeter. With the engine cool and the side panel off, remove the radiator cap and put one meter probe in the coolant not touching metal. Touch the other probe to the battery negative post. The meter should read less than 0.3 volts DC. More voltage than this shows that the corrosion inhibitors are depleted and the coolant needs to be changed. (Works on all engines--cars, etc.)

You should take a good look at all the gizmos the previous owner installed. If any of them are grounded to the frame, disconnect them. Run a negative wire to the battery negative post and connect all these wires to this negative line instead of to the frame/ engine/radiator/whatever.

Good to know

Thanks for the tips, very much appreciated, yes the LEDS had twin core wire running to each of them.
