Wanted / Re: Yamaha CDI with alloy case, two wire pulser with high and low charge coils wires

« on: June 20, 2020, 11:44:02 am »

Cheers over the hill,

I have a loaner cdi for the weekend to run in a new bike to my YZ family, also find a better pulsar coil and installed that as well.

I have brought two cdi's new out of the UK, but both have failed to throw a spark as yet on two different capacity bikes with same stator and rotor combo.

Hoping the better pulsar coil is the answer to that issue, when testing.

But already thinking I might get a single wire pulsar cdi from a YZ250C and ground the white/green and see if that's a resolve are not.

Hearing on that, I have Elsinore's and YZs

My Elsinore's over 35 years and multiple bikes, I have had one source coil fail and that was must likely water damaged prior to me buying the bottom end and running with the stator
also had a issue with advance curve on one, tried all new electrical components which didn't fix it, plugged in a early 80's Suzuki RM cdi ( some stator manufacture )  and presto advance and retard curve for my big bore & stroker not a 125M. "sweet now"

YZ's on my thrid cdi failure, YZ B models with the CDI at the steering head are a issue for sure.

Pulsar coils on the DT360, MX400b to YZ400C so hard to find.

but with all that we keep doing it and coming back for more.

I have often thought, the 70s was a great era in regards to parts available today, dealers posted orders for parts and ordered parts that come in bags of ten.

The 80's saw a charge in logistics, fax machines and dealer stock levels.

The 90's saw a charge where you paid a deposit on the parts awaited for it to come from ex east.

how there's no dealer stock you pay in full, and in WA " Wait Awhile " is very true.

my Elsinore's still have a good supply of parts today 47 years on thank you to the internet, trying buying water pump parts and rear shockie and or fork parts, and power valves in 17 years time for early 90's bikes.

Buy up now and keep what you have but " Ride them don't hide them" and keep living the dream

FYI

So after looking though my Yamaha service data book and various web info.

the TIA 01 - 02 XXX cdi is the earliest production model I can find, this is a 1972 model.

the TIA 01- 06  XXX is a 1973 up for early mx and yz's to 76.

Putting the TIA 01 - 03 211 some where in the middle of that era.

so
TIA 01 is single cylinder
TIA 02 is for twin cylinders
TIA 04 is for the might inline fours

Also found same info suggesting its for a GPX292 snowmobile ( the X in the model code appears to be CDI models ? ), but I could only find a 1975 SR292 with a similar alloy case CDI with six wires in a parts diagram, also for a single cylinder.  all the single cylinder snow mobiles prior to 75 appear to be points ignition.


Black   = ground
Brown =  source coil
White/red & white/green = pulsar
Orange = HT coil pos  or cdi output to coil
and black/white = kill switch.

This TIA 01 - 03 211 is likely for a external flywheel been it only has one source coil input wire not an internal rotor style cdi which has two source coil inputs been brown and red ( low & high speed )

please add if more info comes to light.

I had an issue with my 73 SC500 ignition and used a it250 one for a long time.

Just fitted a 74 SC500 ignition to my 73 SC500 motor.

Looking forward to testing and seeing with the additional weight over the IT250 flywheel has on the power delivery.

cheers, thank you for the response .

HI Marcus.

I can see the white/red and white/green pulsar wires and the brown low speed coil wire but the picture doesn't show the red high speed wire, doe's it have one?

the TIA01 cdi's come in several versions all have a two digit number followed by a three digit number, your one has a two digit number of 03, I am looking in that model code identifier.

I am looking for a TIA01-06 models such as YZ125 74/75 MX250 1973- 75,  MX360 73-74, YZ250 & YZ360 A/B also YZ125C, all have black harness conduit

TIA01-01 is a DT2MX 1972 cdi this model has black conduit.

TIA01-08 is a SC500 1973/74 cdi this model has blue conduit.

TIA01-10 is a MX175 1973/74 cdi this model has black conduit.

TIA01-16 is for YZ125X YZ125D YZ250C  YZ250D cdi this model has blue conduit and only one pulsar ire been white/red.

also Where in the world are you ?
