Hi Just bought some DP mirrors for my 1198 off ebay but I may have been done - one of them has a really fast flash rate. Does this require resistors to slow it down? It's weird because it's an LED indicator replacing an LED, I'd have thought it would be a straight swap. Both wires have been patched up with electrical tape though so who knows what's happened before I got them. I'm thinking I might butcher my old wires from the old mirrors or else just get proper new ones
I put the dp mirrors on my 848 a few months ago and the flash rate was spot on. I bet you've trapped the wires between the fairing support and the top fairing. This would cause the fast flash rate. Try pulling the mirrors off and making sure the wire isn't going over any of the ridges inside the fairing support. Ian
Ok what was the bike condition when you tested, ignition on or engine running? If ignition on only try starting the engine and trying again and don't ask I don't have an FFFFFF'n clue either Let us know if that solves it or we need to look at something else One more thing are the rear indicators the stock bulbs or have they been replaced with LEDs too?
Rears are unchanged bulbs, the indicators are fast with engine running or on ignition only. I think the rears speed up too. The left one works fine. Both have a lot of extra wire, added with electrical tape. Thought i might try taking the connector from my old mirror and see if that works... I may just go back to the old mirrors, these are slightly less blurry but tiny, rear visibility is still pretty much zero
If there bodged I'd certainly get some decent plugs fitted but I don't think that's what at the route cause of the hi flash rate. I seem to remember a thread where @arthurbikemad & me were talking about this problem. I had the hi flash rate with mine but only when the ignition was on, engine running was fine, but I'm running LEDs on the rear too. I could be wrong but I think arthur had or knew of a problem similar to yours. Maybe he'll chip in. You could make up a little test rig with a couple of connectors and try various resistances in parallel to the mirror. I'd get something like 0.25, 0.5,1, 5,10, 20 and try them to see if it makes any difference. I agree with @johnv it could well be the canbus that's screwing it up. This may be worth a go/of interest to you, could well solve the problem and save you dicking about with resistors which are a PIA and liable to melt things if not sited carefully How to "Hidden Service" menu on 848 & 1x98 Part 1 - ducati.org forum | the home for ducati owners and enthusiasts
thanks for the service menu link, I'll have a go at that and if nothing happens I'll just go back to stock, not keen on resistors melting things
they're both LEDs. I'll check stock vs DP again in the morning. Maybe should have gone with new instead of ebay
As said I did indeed have the same problems and at the time so did many others. In short the main issue was for some reason the polarity was wrong on some DP indicators, odd as they are a genuine Duc part you may think, no so odd as the polarity is set by the Dash/can bus, seems that the can bus is easy confused and causes a problem with DP mirrors I.e flash rate and or polarity. It gets weirder as mine somehow swapped the problem in the early days of fitting them, when I added a new dash I needed to swap the polarity again back to how it was shipped, no issue with flash rate on the new dash so maybe Mr Duc updated the firmware on later dashes! Who knows! Oddly the problem seems to solve its self from what I recall when aI first fitted them. My setup now is I run load resistors on the rear and DP mirrors, full system ECU and I've not seen the issue for yonks. Daft suggestion but go for a ride and see if they sort them selves out, mine did, may take a while for the Dash to register the flash rate? Edits, poor memory haha
Thanks for chipping in @arthurbikemad Mine to seem to have got better, I'll need to check and report back, if that's just imagination or not. One more thing on the rears its definitely bulbs and not LEDs in the rear bulb holders and the bulb wattage is standard? I know this is anal but I went through a similar exercise trying to diagnose a mate's flash rate problem via the web one time on another marque of bike. It tied me up in knots and I just couldn't figure it..............then he announced he had upped the wattage of his bulbs.............LOL. The dash diagnostic thing might help, I don't know but although it states for rear indicators, the front and rear are merely paralled in circuit so it may help, nothing to loose I reckon. Be interested to hear how it goes
I did 100 miles yesterday, didn't sort themselves out - 1st 2 flashes are ok, then double speed. (Normal bulbs on the back) Left DP is totally fine. I might try messing with the polarity, maybe the previous owner had polarity issues which don't match mine, might explain all the electrical tape... thanks for all the suggestions.
You need to put a resistor in line....without looking im sure ive got a couple spare....if you want them let me know and ill put them in the post....buck shee.
Saying that alternatively you may have a setting on your dash where you can select "LED" for an indicator type - the series one hypermotards had this function the newer ones didn't - no idea why but there you go... Just to add I saw the first post, thought I was the second to post, posted and the rest popped up....it cant hurt to put a resistor in....one resistor will cover the front and back of one side of the bike....which is the reason I have 2 spare as I bought 4 for my zed 1000, fitted the rear which then started the front flashing correctly. I have integrated rears into the back light and led fronts...
