I washed my bike and rode it after I dried it off today. After riding for about 1/4 mile the engine and battery light came on. Bike was running fine. Went home and pulled the code p0562 low battery voltage. I searched the forum and after reading some threads I checked the battery cables, ground and regulator plugs. The battery cable bolts turned about a half turn but seemed tight. I unplugged and replugged the voltage regulator plugs and checked the fuses. I cleared the code and rode it hard for a while and no lights or codes. I just did my 10k service but didn't mess with anything electronic other than the main fuse. Were the cables the most likely the culprit, or maybe the wash? I want to ride to work but want to avoid getting stranded.

 

I would check youre relays for corrosion. Just went through a similair situation after washing. $10 relay was to blame, as has been the problem for many others.

 

Thanks! I did notice some slight corrosion in the fuse box. I will check/clean the fuses and relays tomorrow.

 

So I pulled all the fuses and relays last night since I had the battery/engine warning light issue after a wash. The fuses had quite a bit of white corrosion on them but the relays looked fine. I replaced the fuses that were really bad and cleaned the rest. I used dielectric grease on each one before reinstalling. After this I cleared the code I was getting and now the bike runs fine. From now on I will keep an eye on the fuse box to make sure everything stays clean. Thanks for the help RLE!

 

i seriously dont know why people wash their bikes with soap and water. i have never washed mine since bringin it home in 08. this is all i ever use!



F water!

 

Ha Ha. Typically I do just wipe it down with spray cleaner, but after I did my 10K service last weekend, I felt like getting her nice and clean. I'm just glad I have my service manual and this forum so I don't have to pay Dallas HD my life savings for a simple fix like this.

 

because even pollen is hard enough to scratch the clear coat if you don't knock it down with water first. Getting it wet with polish probably helps some.

 

When you get a chance, use that dielectric grease on every electrical connector you can get your hands on, but just a little bit, it doesn't take a lot to do the job, just enough to coat the connectors.
This was one of the first things I did to my '09, I've ridden in downpours, and wash the bike with soap and water and haven't had any problems.
