Series regulator to replace our failing parallel regulators

[HAMLIN]

I find this thread puzzling. In 8 years of Tiger repair and maintenance (5 at a Triumph dealership) I have never replaced a R/R on a Tiger 1050 due to failure. A couple of stators of course, but no R/R's. I have replaced a few with units from Ricks which yield more output to support gadgets, but ZERO failures. Sprint ST's experience failures on 2005-mid 2008's until Triumph relocated the unit to the left side of the headstock (in the airstream). I bring this up because they used to share the same part #. I have never seen a failure on a mid 2008+ Sprint ST. Early failures were heat related when it was trapped behind the fairing.

Not so much worrying about the regulator but the stator, a little on the Tiger a lot on the Speed triple.
Since we have several members who have a electrical background thought getting my answer here and applying it on the speedy would be great.
This bike is on it's 3rd, or maybe 4th stator. Would like to make it the last, since the lights are all off the bike there will be more power shunted. Figured if replacing a 75 regulator will save the 125 stator I'm game.

I think later model S3's come with a different, larger stator/rotor combination. Why not update yours? The stuff is easy enough to find on eBay.

Indy,

Your logic is solid and your investment is justified.  I might add that one of those series regulators is rated for fifty(50) amps  so any "new and improved stator" would work just fine.  The old shunt R/R would need to be replaced anyway.  Got any info on the "new and improved" stator?

Hi I thought I'd add to this thread.  My regulator is going out as noted by the diagnostics at the Triumph dealership. I contacted Jack at roadster Cycle.  He recommends the updated SH847 version. 

(I quit selling the SH775 because the SH847 is a much better unit and Polaris was trying to rip me off because I was selling so many back in the day. I was paying about $75 each and was buying a lot then over night they raised the price to $145 each. Greed at work. Polaris wants almost $200 a piece now. I’ve been running the SH847 on all the Tigers. Also the SH775 is only a 27 amp unit, the SH847 is a fifty amp unit.  You can still buy the SH775 at the Polaris dealer, do not buy it on Ebay or Amazon as 99% of them are fakes.) (Jack)
