After reading of so many battery and for some the associated root problem Rectifier/Regulator ( or RR for short ) failures, it seems i have now become a "member" of this club. Not impressed at all, while the battery is the original from my bought new in mid 2000 TLR, it is damaged from undercharging rather than outright age failure. The RR outputs around 14V at idle ( the headlight is wired on all the time on the Australian version of the TLR ) falling to sub 13.8V as the motor is reved.
Being an electrical engineering person i will sort this properly, hence my post here. The RR's from Shindengen are normaly very reliable, failures would be the odd rare unit failure or the more usual incorrect application of Shindengens product, as is chronic on Honda's ie CBR600 and VTR ( the later by the way on some models use the SH579A-11 as oppossed to the SH579A-12 of the TLR 2000 ).
Is the SH579A-12 used on all year models of the TLR up to 2003? Reason i ask is that i will not use a SH579A-12 again either used or new spare as it is obviously not a correct application on the TLR. Suspect the mounting position and the hard wired headlight to allow less power dissipation internaly for the RR. Looking at Shindengen RR's of the present i see no offerings in the SH5xx series only SH6xx and the FET type FH001, the later may well be a synchronous FET rectifier and would be a real stepup towards a more robust design than the shunt SCR type as the SH579 is.
Outwardly the SH678-12 may well be a better replacement than the oem unit on the TLR, though not having seen one i cannot say for certain as yet.
The factory manual i have seems not to have the alternator output power in the Data section, anyone have a figure for the TLR?
The battery replacement seems to be restricted out here as i normaly use the very good Deka power sport batteries for all my rides, seems the special squat size format of the TLR battery is a problem in finding a Deka to suit.
Will bench test the removed RR this week, though there is little doubt in my mind the internal voltage sense phase control circuit is faulty on the RR as removed from my TLR.
Any information from other will be appreciated, likewise i will post the outcome of my solution.
