need some sage advice please ...
Rectifier on my Ducati Monster S4R blew. A common upgrade is to go with a Shindengen MOSFET regulator - usually the FH012AA or FH022AA. There's a new rectifier out - the SH847AA which is a series style MOSFET so it places less stress on the stator and opinions seem to be that it's an even better choice. The price difference is negligible so I went with the FH847AA. Unfortunately though it's slightly larger so doesn't fit into the usual location (under the seat) so I'm considering alternative mounting points and need some help.
Option 1: place it on the left of the front cylinder, behind the fan (pics 1 & 2).
Pro's are it'll get plenty of cooling; because it's down by the engine it doesn't look out of place.
Con's are I'll need to make up a bracket but that shouldn't be too big an issue; not sure how hot the regulator will get and whether that will be an issue for the cable that will sit behind it(see pic #2)?
Option 2: place it under the rear subframe. This seems to be a common alternative (pics 3 & 4).
Pro's are it'll get plenty of air cooling; I can mount it with bolts and large washers so won't need to make a bracket; I'm planning to chop the rear tail anyway so another option would be to mount it to the back of the number plate?
Option 3: mount it under the lower tree on the forks (pics 5 & 6).
Pro's are it'll get plenty of cooling; there are already two bolts there (see pic #6) that just happen to be perfectly spaced so no need to make a bracket - just need slightly longer bolts.
Con's are it's noticeable and doesn't quite look right but maybe only to my pernickerty eye?
Option 4: mount in the tool-holder compartment on the underside of the seat (pic 7).
Pro's are it won't require any brackets.
Con's are it'll be pretty much jammed in there and I'm not sure how hot the regulator will get and if it'll melt the plastic or needs air flow to keep it cool?
Every option will need me to extend the loom - I'm happy soldering etc., … but I'm no auto-electrician so not sure what gauge / spec cable I'll need or if there are any limits on length etc., …?
Appreciate all advice
