30 amp fuse failure


docc

Recommended Posts

After reading docc’s concerns about leaving the 30 amp fuse in place while charging, I checked mine.

Attached is a thermal image of my fuse set after 24 hours on a battery tender. No heat to worry about

Somebody is hi-tech ! What do you get after start-up and the alternator is recharging the battery . I've got a Flir , just never thought of looking at this .

The Flir was a gift from a buddy that is a sales rep but it has come in handy.

I am not electrically minded.

A good question..... I'll check it out in three next day or so and report back.

and I'll probably do the same check on occasion going forward.... it may help preempt problems. I figure once resistance starts affecting any contacts, it will probably be a cycle of more resistance = more heat = more resistance and so on.

I looked it up . It looks like it is a neat toy !  I bought  one a pretty long time ago and it was pretty expensive but it is neat to have to find poor connections  or things "staying on" for battery drain.

It would be interesting to see FLIR images of the fuses and relays after coming in from a ride . . .

  • 3 weeks later...

As requested, after a 40 minute ride back from the pub after an emergency beer (or 3). No IPA today sorry Tom!

Same view from RHS of the bike:

 

Max temp reading I could get was 49 C (120 F) between the fuses (for some reason, I don't know, but the fuses were cooler than the underlying area... maybe its the input wiring temp????). Anyway thats hot, but not so bad I think. I could easily keep my fingers in the area without excessive heat. Image taken from the right hand side of the bike, same as the photo above shown for reference.

 

Just adding that the dark areas are the fuses and the bright is the area beneath the fuses.

View of the front of the engine with the Rectum-Frier (Rectifier) being the dark purple colored item center right of image just to the right of the cross hairs and almost touching the cross hairs. Note:.... A new Ducati rectumfrier was recently installed.

Hot header pipes left and right.

Big blue circle on LHS and partial blue circle on RHS are the horns..... so I didn't have to blast any idiots on the way home!! ;-)

ECU image from RHS of the bike.

Brightest area at the cross hairs is the multi pin connection feeding power to the ECU.

Rest of the ECU box is dark blue / purple.

 

Bright area under the ECU is the negative cable from the battery

View of the front right hand side of the bike from a couple metres away.

Really cool to see the heat in the tires.

A couple more views from the rear  

Hot down the exhaust pipes (Mistrals) And the rear drive looks warm too.

Shiny bright bits up front are the rocker covers.

Warm (not hot) rear tire

Closer view of the RHS rear drive and rear wheel.

 

Conditions:

Ambient was around 25C (80F).

The ride was quick with a blast up to 160kmh for a few seconds on the freeway (thank heaven I am not back home in OZ or NZ!!!) and the rest of the ride was pretty easy going so the bike wasn't really being pushed hard at all.
