2008 S4RS fried regulator.... your thoughts?

[brad black]

it's more about who i buy it from.  wurth talk in mm2 which makes no mental picture at all to me and the reps have no idea either.  bursons talk in "it's about 5mm, maybe 6" which makes not much more of a mental picture.

i have some from jay-dee that is labelled both 2.90mm2 and 5mm, seems to be about AWG 12.5 gauge.  it's about 2mm dia without insulation.  i usually use 2 of them in parallel for reg to battery wires, both pos and neg.  bypassing the original loom usually buys you at least 0.5v at the battery, and sometimes they pick up more than seemed to be on offer.

i have other stuff that's 3mm diameter ish without insulation.  i guess that's around 10 gauge.  

the problem is the maxi fuse terminals i can get seem to suit a single 14 gauge or (looks like about) 2 gauge.  having trouble finding one in between.  actually, i think jay-dee have them.  i'll see what arrives.

Mm2 is cross-sectional area, not diameter. Don't get that confuzzled

this guy also has them with the option of partly made kits - http://roadstercycle.com/Shindengen%20FH012AA%20Regulator%20upgrade%20kit.htm

i have been meaning to get some as i usually have the original style sh579 on the shelf but am out of them and had thought of going to the mosfet.  but have never quite got there.  if suzy says it's a good idea i guess i should.

suzy: do you have any thoughts on the roadstercycle man's use of ciruit breakers as opposed to an inline fuse or maxi fuse?  he thinks it's a good idea.

the jason fella has a kit with wiring and maxi fuse too, and some bad words to say about circuit breakers - http://www.ebay.com.au/itm/SHINDENGEN-MOSFET-FH020AA-REGULATOR-RECTIFIER-KIT-REPLACES-FH012AA-/360451544102?pt=Motorcycles_Parts_Accessories&hash=item53ec961426

i like to go thru the original maxi fuse holder, but terminals in the right size to take two of the wires i use seem hard to get.  maybe i'll ebay that too, although it makes it hard when you don't understand electrical wire sizes.

i have been using this setup with the circuit breaker for some time now and it has been faultless. the shin' mosfet regulator barely gets warm on my bike and it is in virtually the oem placement atm, ie fins up. i personally wouldnt recommend using the original reg/rec again when u compare the price, ease and reliability i have had from this one. it has me completely care free about my charging system now, tho i do still have a voltage indicator led fitting just incase.

Thanks again everyone for your input and suggestions for alternative repairs (to the original equipment).

The wash up is that the dealer did order another genuine part from Ducati and installed it. I got the bike back yesterday & it seems to be running perfectly again. All up, the damage was $333. $218 for the regulator and the rest for labour.

I now know that if I get stuck with this issue again, there are other pathways that I'll try first, but at least it should be perfect again for some time.

And as for the offers of free parts and free assistance to get them installed, I'm humbled. Thanks a million, even if I didn't take you up on these on this occasion.

See you out there.................

Realizing you just got your bike back from the dealer and it's now running fine and "if it isn't broken yadda yadda yadda..."

I'd seriously think about taking some of those locals up on their offer to help relocate this new, functional R/R to a place with better air flow to keep this from happening again.

It fried once in this spot. It's probably gonna happen again eventually unless you do something to prevent it.

It's hard to argue with your logic there Buckethead............
