[QUOTE="dcarver, post: 1368069, member: 956"] Trust me Fred, I can break shit. Just ask anyone. I have high ambient temps where I live. And hills. And a AAA card! I'll PM him, Thanks Rich. Idle is fine, no noticeable drop. The first time, it felt like the high altitude sickness ECU that came on early FJR's. Still running but not much power. No big crankshaft slaps like ignition failures tend to present. Regarding fuel pump, I tested both the 2013 and 2006 when things were 'normal'. The average draw is 3 to 3.3 amps, steady as a rock. When the DL650 was having fuel pump issues, it easily brought max charging voltage down from 14.3 to ~13.1 steady state. BTW, the Suzuki charging system is much cleaner and with more reserve than the FJR. Clean as read on a scope. Well, since I happen to run a Metrology Lab, I'm pretty sure I can source a nice small ammeter to do that test. Maybe I'll have the first dash mounted ammeter which will become the envy of the FJR community. Yeah, I tend to agree. Unfortunately, I'm still working way too much OT and can't spend the time. I think I'll try the easy stuff first - [LIST=1][*]Check diagnostic codes (TPS?) If not fixed (INF) [*]Swap gas tanks, test. INF - [*]Put ammeter on charging circuit ride to failure INF - [*]'Let it Develop' - Fred's version of ride the bitch till she breaks! [/LIST] Thanks for all the advice guys! Don [/QUOTE]
