Hi Folks,
My Interstate would not start yesterday (first time in 5 years!). Found no spark, and after a bit of diagnosis, it looks like one of the windings in the ignition impulse generator has packed up.
Just like to know if it's a known problem, just in case I decide to buy a used one from Pinwall.
Won't know the price of the part here in Ireland till tomorrow, but could be $200/300 against $15 for a used in Pinwall.
Regards,
Valkeire

The impulse generator needs 9.6VDC to fire. If your battery is going out, you may not have enough VDC to fire the bike. Either put a trickle charger on the battrey or jump the bike from a NON RUNNING car battery. The alternator in a car is too big to be fed into the bike's battery or wiring system.

It's NOT common...though I've heard of a few.
As in the previous post, make triple sure your battery is up to the task. Many have the "umph" to spin the starter but the voltage drops so low as it's doing so that the ignition won't fire.
HDL sells the part for $69.62us...not sure what they'd charge to ship you one to Ireland

As above, make 100% sure the battery is good. Mine spun the motor, but would not fire. Runa trickle charger all night, no go. Put a new battery in, all is perfect. Fixed. A weak battery is often overlooked.

Hi,
Good point about the voltage. But I think the problem started to appear in the past weeks.
Two weeks ago, again on a Sunday morning, fully kitted out for a -3C days riding, sat on the bike, which unfortunately lives in the open, engine spun over well, but it did not fire.
Left it for the morning, and went out again and jumped it off my wife’s car. No luck. Brought in the diesel car and used a heavy duty set of jump leads to the bike.
It spun for a while like a high speed turbine and then it started and ran well when on trips. Had to do the same again next time I used the bike. So, the extra voltage worked to get it started.
But this Sunday nothing worked. Got out the manual and the multi-meter and went looking at the circuits. Had a bit of a problem working out the wire positions on the Ignition module. Found nothing, but eventually checked the impulse generator windings.
Multi-plug was easy to get at (behind the plastic cover on the front right side of the tank, 4 wire white plug). Disconnected the plug, and connected the multi-meter across each of the 2 pairs of wires and spun the engine over.
One set was showing a resistance of several hundred ohms when stationary, and 1.15v on cranking.
Manual says at least 0.7v. But the other set showed resistance in the Mega ohms range and showed no voltage when cranking.
So I’ll replace the sensor and hope it is the cure.
I do a lot of solo riding and need the bike to be absolutely reliable, which it has been 100% for the past 5 years.
I’ll check with HDL about the part, the cost of parts in the USA is very reasonable, but international shipping is a nightmare.
Most places simply won’t ship internationally, and many of the one’s that do charge high shipping charges. A $70 part could cost $90 in shipping, which the combined total is then processed by FedEx, with customs duties, handling charges and the sales tax of 21% added to the total. Ouch!!
Though I must say I found Pinwall to be half reasonable (as we'd say in Ireland).
But happy to have found something definite, but wasn’t easy working outside in freezing temps of the Irish kind.

There's your problem, right there! -3??? Seriously, that tells me that borderline battery plus cold temps yields a no-start condition. I'm not seeing anything from your description that disproves that. |

I'm not seeing anything from your description that disproves that. If he is doing the voltage checks on the pulse generators correctly, then the "no voltage" on one pulse generator would be an indication that it is malfunctioning. That is assuming the proper peak voltage meter was used. The pulse generators do not require voltage to out put a signal, they create their own. |
