Electrickery / Re: Loose coil-spark plug conn...
Last post by TigerShark - May 06, 2025, 08:34:31 AMForgot to mention, the spring in each coil actually does not grip the top threads of the spark plug, though it does encircle them.
The solid contact with the top of the plug is made during the bolting down of the coil; the downward pressure of the coil loads the spring against the flat 'shelf' that runs around the base of those tiny top threads. That is the spring seat when assembled.

Last post by TigerShark - May 06, 2025, 08:20:01 AMWhen running the primary test on my coils, I was metering .4-.5 ohms resistance. Considering that .1 ohms of that is attributable to my Klein test leads, .3 ohms resistance is quite out of the .7-.9 Triumph spec.
I went ahead and ordered a set of coils from RM Stator. Being in the state of Washington, their Colorado headquarters will have the set to me in two days.
Until now, I never thought of coils as wearing out. Always learning.

Last post by Lee337 - May 05, 2025, 04:33:09 PMI'm no expert on these & wouldn't even know how to check them without the help of the internet. I've been lucky not to need to replace them. The internals do break down after a while, the life expectancy is around 100k - 130k miles, or 7 years. Having said that, my 06 didn't have a problem & I had an 05 with 123k miles which was fine. I've heard 130k+ milers still going strong.
It might be something as simple as all electrical connectors needing a good clean & maybe some electrical contact grease (think it's called dielectric grease).
Sadly, finding replacements may be a bit difficult. Triumph show them as no longer available (part No. T1290006).

Last post by TigerShark - May 04, 2025, 04:59:38 PMThank you, Lee. Your comments support what I've always understood, but the fact that all three of my coils lack that assuring friction during installation really made me wonder if these 955 coils relied on an unconventional means of contact.
By the way, these coils with 123,000 miles on them, including many hours of stop and go heavy traffic, are each at about .5 ohms resistance across the two connector pins. According to my manual, spec is .7-.9 ohms. My meter is a quality unit. Any thoughts on this?

Last post by Lee337 - May 04, 2025, 01:17:07 PMYou should feel some resistence when pushing the lead on to a spark plug. This indicates it's seated correctly.
Sounds odd, but a loose connection can allow electricity to leak. There should be good contact to avoid this. Leaving it loose could ultimately cause a misfire or rough idle. I had this on an old V6 Shogun I owned, which eventually eroded the connector. Had to replace the HT leads but to get me out of a jam, a good clean with some wet & dry, a spray with contact cleaner and a little tweek with pliers resolved it.

Electrickery / Loose coil-spark plug connecti...
Last post by TigerShark - May 03, 2025, 05:51:29 PMOn my '06 Tiger, I was surprised to observe that the spring in the coil that pushes onto the small threaded top of my NGK spark plugs fits so loose that I feel no resistance when connecting the two. I did this while holding the plug in one hand and the ignition coil in the other. Same with all three coils. In my experience, there should always be a tight connection, producing a notchy resistance when the coil is pressed onto the plug. Any insight on a misunderstanding on my part? Or is this normal wear, requiring a squeeze with needle nose pliers?

Girlie Charging Woes / Charging woes Pt #20495
Last post by sipsmi - April 30, 2025, 10:17:03 PMHello all.
Not ridden for years (27) and got the bug.
Ended up with a 2006 Tiger 955i which has a few things to do and not really been used for a couple of years ( 60 miles to and from MOT testing station).
Changed fluids and checked over, and been up and down the road a few times then I hit the New Forest for an hours ride around. On the way back ( near home thanks goodness) dials died and then whole bike died as I got in the drive ( lucky ) . Turned out I had a flat battery so starting looking at the forums here and some diagnostics.
The stator, off-load - has the same impedance between all windings ( not shorts ) - shows 20-40Va/c with revs but lowers right down when connected to the Regulator. Battery seemed to charge from a battery charger so I wired in a replacement regulator to see if this was the problem. Disconnected from the battery the regulator is showing around 15VG output. Connected to the battery it does not seem to charge it - down to 12.1V running.
So either the stator is no-good under load or the battery is not good given that I swapped in a new regulator. There may be an intermittant issue though as at one point when I was testing it actually ran up to 13V ( 14.5 when revving ) but then settled back down to not charging ( around 12.3V and dropping).
The bike has the modification where the output of the regulator goes directly to the battery rather than through the harness and fuse box.
Woould a dodgey battery show this sort of fault ( no way of testing it myself other than it cranks fine and lights etc are consistent brightness etc, .
Any hints would be gratefully received otherwise I guess its replace the damn lot ?
Cheers

Girly Talk (1999 - 2006 Tigers) / Re: New Owner of a Girle!
Last post by Lee337 - April 30, 2025, 05:12:11 PMMy Girly sounded like a box of spanners at idle, My Tiger XC sounds the same & my Trophy sounds like a tractor, so I think you're in good company.

Last post by London_Phil - April 29, 2025, 03:52:01 PMWelcome... Bag of spanners you say....judging by my Steamer and my 800xc its generally normal., but there are plenty here to help if needed.

Girly Talk (1999 - 2006 Tigers) / New Owner of a Girle!
Last post by Jackelopeus - April 29, 2025, 01:28:57 AMGreetings everyone. Just picked up a 2000 Triump Tiger 885i! She's a bit a of a basketcase at the moment, but couldn't pass up the chance to save her from the scrapyard. Unfortunately, she sounds like a dryer full of gravel at idle, but off of idle goes like a champ. Something normal for this bike, or did I get a dud? Oil and other fluids look to be fine.
