Hello everyone,
I apologise, this is a long winded post, I have a DL650 AL2 with electrical gremlins..
I have trawled various previous posts regarding this issue but I'm struggling to find a solution. In short, the LCD screen doesn't light up or give a reading and the rev counter doesn't do it's start up sweep. The neutral & ABS lights are lit though.
To start from the beginning.. I normally ride all year but this year, owing to work, I wasn't riding that much and the bike has sat more than I would like. Come January (during the cold snap) the bike is a bit hesitant in starting, charge the battery and although it starts it's intermittent. On one occasion the F1 light shows and I get a fuel pump error where it doesn't prime, thinking the battery is kaput I buy a new one and everything is fine.
The bike then sits for another few weeks (Since January we have had a baby so riding is limited until they invent a car seat for the pillion!) and on trying to start it the F1 light appears again and the same error. Strip it down & check all the relays etc but can't find a problem. Put it back together and it starts fine, take it for test rides and still no issues.
Then, riding for a funeral escort and in heavy rain, stop at the motorway services for others to get fuel but when I tried to start my bike the F1 light appears. Not only that the clocks start to be intermittent and not light up. By this point I'm wondering if it's the connector under the air box so myself and 1 other strip the bike at the services to check the connector, it's manky but not excessive.. When prodding and poking I noticed that the wiring loom by the battery will cause the F1 issue to disappear & the clocks to light up. Not having the proper tools to delve into electrics I admit defeat and call the AA who eventually recover me home. I thought I would try starting it when I got home and the bloody thing fired up but due to the time I switched it off and left it.
I have since stripped everything down and opened up the harness where I found a corroded connector with 4 wires becoming 1 red / white wire. This was completely trashed so I stripped them back, extended the single wire and fitted a new connector. This has fixed the fuel pump error but now I have an issue with the LCD screen..
The neutral & ABS light comes on but I don't get the red oil pressure (?) light or the ice warning light and the speedo doesn't do the start up sweep. The LCD screen is also dead and does not show any text.
With a 3 month old baby my time is limited in the garage and this is starting to be a rabbit hole!
I have used my multi meter and checked continuity for each wire between the ECU and the LH fairing connectors, all showed a connection. I also checked the continuity between the LH fairing and LCD connector, these also showed a connection. I have had the whole LCD unit off and the pins are bright with no signs of corrosion, the boot was well installed and taped up, just to be certain it spent a few hours in a baking conservatory.
Has anyone else had similar in terms of the LCD screen? I am checking the various bits of wiring loom but I can't see any obvious breaks or burns. Are there any tips to spotting a broken wire if the insulation isn't damaged?
I am currently awaiting a new 10 connector and will replace the airbox connector as I can't get the pins out easily, once I cut it open I can clean all the connections up. The battery is only a couple of months old and is fully charged.
Thank you for taking the time to read this, any help would be greatly appreciated. I am reaching my limit with this issue but feel the answer is staring me in the face.
