On My Lectra project I've used this solenoid: L Series Solenoid Heavy Duty Switch 12V. It's rated for 250A continuous and the ratings overall seem sufficient for this motorcycle. But over the weekend I discovered it is 'ON' regardless of whether the coil is receiving current.
Anybody have experience with this sort of thing?
I suspect the solenoid contacts are welded shut. The only idea I have is it's rated for a max of 60 volts, and that's the pack voltage on this bike, meaning it's running at it's maximum.
I've looked at evparts.com with the solenoids they have.. and I see a couple with similar amp ratings (250A continuous) but with a higher rated voltage (120v). Those are affordable, but the ones which are rated for 400A are extraordinarily expensive.
