Hey guys, quick question for you guys. I saw the list of what all the speedometer codes mean that are listed up top. All of the lights are working just fine but the speedometer and odometer sometimes cut out. Any time that it cuts out, the speedometer light is still powered. The error codes I'm seeing are d08set (speedometer power over voltage) and PPL108181 (couldn't find much on this one). Any ideas on what can be done to work on this? | ||

A bad voltage regulator will cause this. Use a multimeter to check voltage during idle when the speed/odo is out. They usually go blank at >15VDC. | ||

Thanks for the response Jetlee. Am I to check the voltage across the battery terminals or in another location? I can probably idle the bike after startup while the speedo is still working, then ride until it disappears then check again to see the difference. | ||

Yes, across the battery terminals. It should only take about 5 minutes of idle (when stone cold) for the regulator to warm up and start overcharging the battery. I advise against riding a motorcycle with a known electrical issue, but I can't stop you. Also if it's the only way to replicate the issue, ATGATT and stay close to home. | ||

Oh interesting, so the problem could be worse than just having the speedo drop out during the ride?? I know obviously that riding with a functional speedometer is the safest way to ride, but especially here in the city and I am rarely if ever the only car on the road to pace myself with. If it is an issue with the regulator, is this something that is an easy purchase and swap? The look pretty pricey from first looks, but that just might be the reality. Basically the only electrical work I have done on bikes or cars has been replacing bulbs, and installing a new headlight and front blinkers on the Blast. | ||

A bad regulator will overcharge your battery. Depending on your battery, different things can happen...nothing, get hot, explode, melt, fire. Mine did nothing but get a little warm for a week, I'll let you weigh that risk. | ||

On ebay I see a lot of Buell Blast Voltage Regulator RECTIFIERs, is this the same thing as the regulator or is the regulator rectifier something different. Ebay has used ones listed starting anywhere around like 30 bucks, then I see them go over 100 bucks. What is a reasonable price, and are these cheaper rectifiers the same thing that I am looking for??? Road the bike to work and back today, and had the speedo drop out and come back in a couple of times, now it kinda flickers on and off. On the way to work I turned the highbeam on and it resurected the speedo and odometer for pretty much the whole ride there. This trick didnt work on the way home though, and now the headlight doesn't work if the speedometer drops out but the blinkers and all indicators on the speedometer work just fine. Might have blown the headlight out? | ||

I think you're flirting with disaster. Rectifier and regulator are the same thing when listed for a Blast. All my price books are still packed, so I don't have any idea what reasonable is. But you will find a great variance in price for the exact same item. They all fit all years. Electronic parts are always a gamble and its a better bet to buy one from someone parting out a bike (or few) than someone just selling one part. Id rather gamble cheaply. | ||

Interesting. Don't want things to go South with this bike all because I wouldn't shell out a relatively small amount of money. Found one on Buell Parts for like 40 bucks, I will probably order that and hopefully that will solve the issue..... | ||

Slapped the multimeter on today. Battery looked fine, then while idling it creeped up to mid 14s. When revving got up to about 16. That means its time to buy the regulator?? | ||
| Gearheaderiko |
Yep! | ||

That does sound too high. 14.8 is about the highest you should see on an accurate meter. Check grounds also. That's a shunt regulator, so a bad ground may make it impossible for it to regulate even if it isn't broken. But it's probably a bad regulator. | ||
| Wrightd223 |
Thanks for the input Reepicheep. I took the regulator off and hit everything with some contact cleaner to make sure it wasn't just a bad connection and then hooked it all back up and that's when I took the readings. You and my dad think alike! I will put an order in for a new one and keep the thread posted. | ||

Alright guys, new voltage regulator came in. I put it on the bike, and checked it out with the voltmeter. Reving the bike the voltage never went over 15 volts (maxed out at around 14.7), so looks like the regulator is working fine?? Took the bike out for a short ride to my sisters, about 2 and a half miles of city driving, but I was able to put the bike into third gear. After hanging for a while, drove the 2 and half miles home. The speedometer never dropped out, and neither did the odometer reading, woohooo! I did run through the system check, and it is still giving me a D08SEt reading though.... and the PPL108181 error code is still displayed as well. Now this was before driving it around, and i forgot to check once I got home, but like I said everything seems to be working fine. | ||
