Why did it take so long to get fixed?

 

i get this code occasionally, but it never happened till i installed my fuelpak. but you say it was in the tach. if so, is this a fix that would be covered under warranty since it sounds like a moco defect?

 

You are not alone. I have a 2012 Superglide Custom with 5,000 miles on it with similar symptoms.

I have V INERR, hard starts with a hot engine, and recently it will randomly stall when approaching a stop.

The scoot has also thrown the following codes: P0507 (ECM mileage) & P1632 (high idle)

Starting issue

 

I've encountered this problem and dealt with it for a long time on my '13 Super Glide Custom. I have around 18.5k miles and just recently I've also had problems with high idling on hot start ups. Last weekend I was on a ride and my engine died on the highway. After removing the battery cover I found the negative battery terminal was melted. My girlfriend and I were wearing heated gear and I thought maybe we were overloading the battery. Then someone at Harley told me a loose battery connection can cause excessive heat and that can happen. I was also told that would explain my engine issues that day.

I put the bike on a tender and found it was running perfectly for the next three days. No engine malfunction, and no V INERR on start up. On day three it was left off a tender and all the symptoms returned, minus the engine failure. I concluded it was a battery issue and bought a new battery. I also read several threads about the V INERR code and saw that many people think it is associated with a bad battery cell, or poor connection somewhere. It's been a few days and so far there has been normal engine performance and no V INERR error. I'm not sure if the new battery took care of everything or not, but so far so good.

 

After a year of dealing with this error I may have unintentionally solved it. I was installing new mini ape handlebars this past week when I had to mess with the main wiring harness connectors. After uninstalling my heated handgrips and literally squirting dielectric grease in every connection in the fork tube under the gas tank, I have not had this VINerror code pop up once, even under ideal circumstances. It's been about 10 days so far. I'll make an update if I get the V INERR code again, but so far so good.
