Vacation 10 days.

F4 1000S, 2006, fully charged before leaving.

Raining, so doing a static garage startup to run the bike.

Press starter button. Click.... press again Click..... Press again Vroooomm, she lights up as normal, running smooth.

So, Battery low? Relay tired? Or just one of those MV things?

Thanks for any reply. :smile2:

Battery low.

The wiring to the relay, the relay connection, and the relay itself, are probably due for a refurbishment also.

Starter Solenoid .. (Relay) -- odds are 100:1 on that .. Especially with a charged battery .. in the locked topic "parts" you can find the replacement parts number, from a Yamaha Quad, I believe :)

If its the Solenoid, it will get progressively worse .. But then again the same goes for a poor ground connection or corroded contacts/plugs.

I recently had a starter solenoid on my R6 that was intermittent. It showed the same symptons that you described above.

If the battery is charged as you say other likely causes could be:

- earth.
- starter switch - may need a clean.

There others but these are my thoughts on the most likely

Come on folks, THINK
If it goes click, click and then starts on separate pushes of the button, its obviously not the battery
There's a loose corroded/connection in the power or ground to the starter
If on one push of the button it clicks repeatedly, it's low battery or bad connection to the 4 wire plug

They're copper connectors held by a steel bolt.......you put 200+ Amps through the resistance
in the connection.....the copper expands faster than the bolt, tightening the connection....
And the POS starts

No fucking shit

Tell us how you really feel Noel. Don't hold back. :wink2:

The smart money says, "starter relay".
Stupid money starts replacing parts.....Smarter money figures out what's wrong>:

Load test the battery....I use an old SnapOn YA-271, if it's good
Turn the key on and short across the solenoid terminals if it starts it's in the control system
If it doesnt on the first try, the cables are loose/corroded, that's both positive or negative
If cleaning that up doesn't fix it, it's in the 4 wire plug or the starter button circuits

Mario;
in 59 years off and on as a professional mechanic and on my personal vehicles I've never seen a bad solenoid

Manufacturers have realized that nothing pisses a husband off more than when the wife calls.....
"My f...ing car won't start"
Delco solenoids have a round contact plate that gradually rotates, exposing new contact area
And it's reversible too:grin2:

Old school :grin2:

Starter solenoid is not that uncommon mate. It wouldn't be my first stop, but it happens. As I said, mine did. What made it alittle more difficult for me was it was intermittent showing the same symptoms as the OP. Doesn't hurt to rule it out.

Point is, you rule it in or out by testing...

And cocky mo-fos make rash assumptions....



But, as long as we're flopping our trouble-shooting dicks out on the table....


I've been riding and wrenching on my own bikes since I was 12. Not to mention cars, ranching equipment, home electronics, guitar amps, and anything else that happens to unexpectedly go clatter or make smoke. I just celebrated my 62nd birthday. Just out of school in 1980, I spent 13 years as a field service engineer repairing computer & robotic equipment. That was when computer repair required knowing ones way around an oscilloscope, and a solid understanding of electronic theroy as well as TTL logic. I moved on after spending the last years of that career as the Western Regional Technical Support Specialist. That title translates to the guy that hopped a flight and bailed out the other guys in the left half of the USA when they got in over their head. I will put my electrical/electronic trouble-shooting skills up against any comer's.


That said, I don't recall suggesting replacing anything. I didn't even offer any trouble-shooting advice, however, if I had I would have advised the original poster that trouble-shooting a relay can be done with a cheep-ass auto-parts store probe, which I'm pretty damn sure is a lot less money that anything on the Snap-On truck, with the possible exception of their fine calendars.



Oh, and finally... I grew up in a tool and die shop, and I know what a knurl is, so the irony of your rough approach to communication is not lost on me. But A+ on the clever self-effacing humor. If that is what it is.

@Mario Landavoz: As a relatively new member here, I think the Old Guard will give you a pass on this; but, learn your audience...and your MV.

The bike in question, and really all MVs has a design issue with the starter solenoid wiring. The solenoid itself rarely goes bad, but the wiring connection to, and the wiring itself, is subject to excess heat from high resistance connections and under rated gage.

Most of these issues tend to be resolved with a good cleaning of contacts, or an upgraded set of battery cables from Motoelectric, or a connection refurb.

This is standard practice for MV electrical issues. Now, if the circuit is sound and the solenoid tests faulty, they can be obtained as cheap as chips from Yamaha.

I have two on my workbench if the OP wants one.

It's generally frowned upon to come in and give a solid :nutkick: to someone you don't really know.

SS703, Point taken. That is an interesting prognosis. I'm happy to learn from anybody.

In any case, I apologize for over reacting. Normally when something sets me off I let my response rest for a while and reread it before sending. I did that in this case, but I had a taste of the Hanger One in between steps one and two. Note to self....

The Knurl's moniker is most appropriate...it's why he uses it, as you figured out.

Mario, I have had my well-documented moments on this forum also.

Looking forward to more contributions from you!

So, cutting to the chase, has the OP tested the charged up battery voltage at rest 12.7 V circa and then done a drop test when cranking...Battery shouldn't drop below about 10V ....If it does then the battery is in need of a dumpster or recycling ....

I have a twin cylinder bike that had same symptoms.

Fully charged

press start button...Click
press again....click
press again...Vroom Vroom !

So I drop tested it yesterday afternoon..

press start button...Vroom but voltage dropped to 8 volts.

Conclusion battery is fkd...Time for a new Yuasa.

I'm going to France for the 100th WW1 remembrance 9-11-18..I don't want to break down out there in the cold.... Tomorrow the new battery will be fitted.

Test the battery.!

Joe
