Im sure its been discussed numerous times but I cant find the answer.

Problem: Lc with 202. Crane cam fireball hi-6 ignition system

Connect the tach output wire to tach. Nothing
Connect a wire from -ve side of coil. Tach reads 2600rpm at idle. Same reading with 3 gtr dashes. Tried a cheapo after market one. Same thing 2600

Tried auto meter one while still on -ve side of coil. Nothing.
Connected it to tach out put. 650 rpm.

I tried 4 different resistors but they made no difference

So my question is how are you guys getting your geniune tacho working when using electronic systems?
TIA

Hi Paul.sorry i cant really help you but
when i got my wiring converted to run gtr
dash Aaron (sparky) asked if i was going to
use electronic dissy ,i said.. yeah later..so
he just mentioned the resistance wire for
points only gives out 8 volts and just
wired in another pink wire for when i go electronic.thinking maybe you will have to
do the same..

That will be so you have 12 volts instead of 8 for the unit

You need a Tach Adapter.  Just make sure you pick the correct one for your ignition type: Points or electronic.
 
8910 is for points, 8920 is for electronic.

I will look into it thanks

Installation Instructions. Maybe someone else can work out how to fix.

I brought a MSD tach adapter today so when it arrives next week I will see if it fixes it

Yep I used the msd tach adaptor on my crane hi6 to run the stock gtr tacho.

The msd ones look nicer than the crane ones too!

Oh.ok..so i will have to get an adapter
aswell bud, when i change to ice ignition
or is this just for the fireball hi 6

I have no experience with ice ignitions but at least they are local to be able to ask them if you have issues.

MSD's & Cranes only really need them with certain types of tacho's ie old Holdens!

The factory tachometers read a coarse signal but the msd 6-al2 gives off a fine signal. The local instrument repair guy in my area did something to modify my tacho and it now works fine (with no tach adapter). I just took the instrument panel to him and he worked his magic.

Bloody beauty. Good to know

FYI
The msd tach adapter has it working like a new one. Happy days
