Starting issue - frozen relay - which one do I replace?

[Iceman31]

I have the issue where the relay freezes and I have to put the hair drier to it so it will allow the fuel pump to run. If I want to replace that relay which one is it? Can I buy that relay anywhere or do I have to get it from a dealer? I am a newbie at this so go easy on me. I have had to do this two days in a row. Temps have been around -20 Celsius. Anyone else have this issue?

Yes mine did it for the first time this AM, hoping i dont have a problem tomorrow because i dont have a hair drier with me.

Not sure what one it is though.

From what I can tell its the second one from the left.Blue,Yellow,Black/white wires.They all are located behind ECU.This is the relay that would turn pump on.If it doesnt turn over that would be the starter solenoid located on side of battery.Not 100% on wire colors but thats what 08 wire diagram shows.Let us know if this is right please.You can swap relays to check since others are same.

I also think it was the seccond one. my pump would not prime but it would turn over. Is there an easy way to get to it? I just shoved my hand in behind there long enough for it to warm up a bit.

I could hear a spark like sound, like a light switch sometimes makes.

Are these relays only available from the dealer? Or are they a standard off the shelf relay? I see on the Yamaha parts breakdown there are two relays 5DM-81950-00-00 and 8FP-81950-01-00. Do you know which one this would be?

I had the same problem 3 days in a row, and I do believe it was the middle relay. I didn't have enough room to slide my hand in there w/out removing the plastic panel on the bottom. Just wrapped my hand around the relay for a few minutes and that did the trick.

I've heard there was an update for this relay, something about updated cold temp grease? If you look at the 2007 parts diagram, it shows 3 relays total, 2 have the same part number and the 3rd is different. one of those relays is now obsolete and the fiche doesn't offer up an alternative. Anybody know what part to order to solve this issue?

Make sure you ask for the updated relay from a Yamaha dealer, $8.00 CDN.

I've never had the problem but bought the relay just to ward off the gremlins, seems to have worked so far.

Call the dealer, they know what relay to sell u. Ill look at mine in the morning to see,but most relays are mass produced for use in many applications, there is a actually an SAE regulation on relays. Im willing to bet you can find a better replacement relay in most auto parts stores. Also if it is a standard type relay, you can replace it with a much better but more exphensive solid state relay which does not reliy on a mechanical to electrical connection.

 

[cannondale27]

Supposedly Napa has a better replacement.As far as solid state relays they work great but have one flaw.They draw a small amount of power themselves.Sometimes this draw is enough to not allow the ecu to turn hibernate.

another possibilty would be to simply insulate the relays.

 

[Iceman31]

what do you propose to use for insulation? Any fire hazard by doing it?

 

[Iceman31]

heading through the city tomorrow and will pick up another relay. This idea of insulating does intrigue me. Does anyone else have any thoughts or ideas on how one would go about doing this? What about using that bubble wrap stuff that looks like tinfoil on one side?

 

[yamahas]

I don't think the insulation will do much. If it's cold it's cold and if it was in the cold all night the cold wil have gotten to the relay. It would keep it warm longer but I don't think the warmth would last the night.

The cold would find it's way through the connections maybe since metal is a very good conductor. The updated relay and maye some dielecTric grease would probably be just fine.

 

[Iceman31]

does anyone know what relay it is of the two that are available? Dealer never got back to me today. Does anyone know of an aftermarket one that I could pick up - say at Napa or any auto parts store?

 

[yamahas]

There was a post in the apex section with the part number for nappa. I will try to find it. Could someone tell us if the apex and Phazers relays are the same?

One thing is that nappa might just have the "un updated" version since all they can do is cross reference with the one that we already have?
