Well my SI Board showed up from Programa. Fairly straight forward swap if your patient and mind your guage needles.
While in there replaced the 3, 3 w bulbs with sylvania 2825 5'w and the headlight and foglight bulbs with T5 L.E.D's
Also thought I would freshen up the idiot bulbs with recommended sylvania 2721 12 volt 1.2w mico bulb.
Plugged the cluster back into the dash everything worked great but not one 2721 worked.
The original bulbs were really tight and difficult to get out and the new ones are in and a bit sloppy.
Anyone with experience replacing these tiny bulbs? Am I using the correct replacement
Thanks,
Iain

Re: Idiot Light Bulb Replacement
If you changed the charging bulb be aware that it's also an exciter bulb to activate the alternator.
Just make sure your charging circuit is working with bulb changing.

Re: Idiot Light Bulb Replacement
The alt light comes on with the ignition turned to position one. I did change it to a 5w bulb however.
I need to pull the cluster to replace the micro bulbs. Do you think it’s necessary to put the 3w back in the alt circuit?

Re: Idiot Light Bulb Replacement
If the 5 watt lights up with ign on and goes out when engine is running,
test to make sure the alt circuit is charging. If this happens you should be good to go.
If not, go back to 3 watt and recheck system.

Thanks for your input.
The alt light does go out once the engine is running with the 5w bulb.
Now to figure out these micro bulbs.
