Electrical Issue?

[ken0la]

Any one else out there experiencing their digital gauge/head light not powering up right away. After I start up, it seems to take a minute before there is enough juice to power them up? Once they light up, alls good.

I've checked both the battery voltage (12.5v) well before start up, and the voltage output (at battery) after the engine is running (14v plus) so I'm scratching my head at this point... javascript:emoticon('')

Sounds to me like a sticky headlight relay. When in extreme cold temperatures I have seen the relays take a little time to start working and that is exactly what happens.

Okay, so both headlight and gauge relay are sticky? Is there a solution, or just let it go as is?

Either your battery is bad or need a full charge. There are no sticky relay, just that the control unit will wait some minimum volts to come back after cranking.

I know that when it's really cold, both my wifes machine and mine do the exact same thing. I chalked it up to some sort of thing built into the electrical system as it happens on both machines. I also noticed it on a few other Yammi's. No one ever had any problems, just took a couple of minutes to warm up and all was well. Personally, I wouldn't worry about it.

Hey Sparks, how old are your batteries? I'm thinking maybe aVenture has a valid point as this just started happening towards the end of last year. Before that all was well, cold weather didn't seem to be an issue. Tricky to nail down really, I don't have a load tester, but my battery does register 12 plus volts on the old meter. I check it often just in case the stator issue rears it ugly head!
My battery is the original 05.

aVenture is probably right on the money. The only machines I've seen this happen on, are the ones with weak batteries. It has to do with the load, and if the gauges and headlight came on right away, it would take away the juice needed to run the ECU, therefore, it remains off until the levels come up. A battery, at rest, that shows 12 volts, is near the point of being useless to start your machine. It should sit at approximately 12.8v. A weak battery is also very hard on the starter clutch.
I have a battery heater, inline heater and an all weather battery tender trickle charger on my sled. In the cold we experience up here, it's pretty much a necessity if you want your 4-stroke machine to start after -30 to -35 celcius. I keep it plugged in when it's not in use. I've seen batteries freeze in less than 2 days up here.
Charge your battery to full capacity and this problem should resolve itself.

Peace!

Zoomsplat is on the money...
In the service manual, 12v no load = recharge the thing... 12.8 = good

If the battery hold the charge, your good to go for the season. ..or in the case it does not last, chances are the "not so bullet proof" stator will get hard time to constantly rebuild the battery, but worst, be on its own to feed peak current at time. I am not speculating on consequences, just telling how thing lines out.

..OH.. for your voltmeter. The running voltage goes to 13.5 to 13.9;

Awesome information fellow sled heads, greatly appreciated.
