Impossible cold starts

Post by snb290 » Thu Dec 07, 2017 7:47 pm



I just got a 96 GL1500. It runs really smooth, and starts very easy AFTER it has warmed up. Even on a warm day, if it's the first start of the day, it is very difficult to get it running. I've tried with no choke, half choke and full choke. Most times the battery is starting to give up the ghost before it gets going.
I'm open to any suggestions. Thanks

You need a strong battery - and all electrical connections to be clean and corrosion free.
Most times a new battery will fix the problems... any history or age of the existing battery ?

Sometimes when the battery is down a bit on charge, you can crank it for a second or two and release the start button instead of continually cranking, it will fire up..

cheers

I just bought the bike a week ago. The previous owner said the battery was new. And it cranks like it is. It'll run the starter for quite a while before it starts to lose power.
And, when I use the starter, I don't run it for any more than 3-4 seconds before giving it a rest.

Thanks for trying to assist.

I had a VTX 1300 R, always in the garage on a battery tender, never had a problem starting it until I went on a trip and it was parked outside on a very cold night. It cranked and cranked but would not start, I got a jump from a friends bike and it started right up. That happened again the next night, got a jump and it started right up again. The battery was good and cranked fast but just not enough power to start it on a cold morning.
Just because the battery is new doesn't mean it is a good one. Battery prices vary from $39.00 to a couple hundred. Check the Cold Cranking Amps of the battery, they vary a lot and make a lot of difference on cold morning.
Next time try jumping it from your car battery, with the car NOT running, if it starts up you found your problem

On the 1500s, an AGM battery is just about a Requirement for easy starts.

Wet cells just cannot hold up their terminal voltage enough to allow the ECM to fire the spark plugs.

+3 or 33, on just biting the bullet, and buy a high capacity AGM battery.

It will start on the first try before you take your finger off the Start Button.

Thank you for your help. I'll be checking that battery first thing in the morning. It's supposed to be 29 degrees in the a.m.. Quite cold for this part of Texas. I'm hoping that that's all it is.

Right around 10.5 volts is the absolute lowest battery voltage that will actually start a 1500.

the starter whirls really good, and you think "it ought to start",

but, the ECM is not getting enough power to fire the spark plugs.

even an AGM will drag down to about ~11.5 volts while the starter motor is turning.

Funny how things turn out. I was starting up my VTX yesterday, and remembered that you use 1/2 choke ONLY. It just won't go if you use any more. Sooooo, of course it hit me to give that a try on my Goldwing. IT WORKED! Cranked right up on the first try. I don't know if it's that way on all Hondas or just the ones I get.
