I have 2 older Shindengen FH010 from ZX10...bought both used on ebay (<$50?) installed both in 2009 on my VFR and Ducati... both STILL in service to this very day, zero issues . Hey, meant to add...a voltmeter is a great addition too. Whether digi or LED, provides instant notification of insufficient charging.
I got an led one on it...thats how i knew it went bad...i looked down saw 11.5 and turned around bolted home
Another great save from the pain in the ass stuck by the side of the road situation, another tick for the voltmeter
