    Just fit the finbro ecu and although it starts ok now, i think it is going to need some help in the colder months.
    Anyone got pics of their cold start switch setup, im not too good with electrics and would like an idea of what im up against
    Cheers
    Jay

    Hi Turp,
    Well the vinyl is quite thick, almost twice as thick or more as the 3M vinyl, its got like 2 layers. So it was difficult almost impossible for it to wrap around the sharper edges and bends of the body because the vinyl wasn't very pliable. I had to do a lot of cutting , trimming, edge hashing and swearing because the fitment was sub par. I rate the fitment 6 out of 10 stars. I used a new razor, heat gun, tennis ball (to smooth, paste the vinyl) and a lot of patience. But I''m satisfied with the end result. 2 years later, it's still holding up (these vinyls are supposed to have a 5 year life span).

    OK grommers, this is one way of building the finbro cold start fix circuit, including the CEL on/off indicator. Pardon the crudeness, but I have no access to any illustrator software, so camera pics only.

    Please make sure the diodes and capacitor are in the correct polarity (do not reverse) or else KABOOM. It's easy to check it. Each diode will have a silver band on one end. The banded end is the negative or ground. The capacitor has a negative (-) label with a directional arrow. Follow the label to ground.

    Solder or crimp, use whatever method you prefer. I crimped all my connections to make it easier if I ever wanted to return to stock. And don't forget to add the heat shrink tubing as you make the connections.

    Special thanks to Nd4spdbh for bringing this to light.

    Parts list:
    wire stripper/crimper, 18AWG stranded wire, cutter, lighter or heat gun, heat shrink tubing (make sure it can fit over the capacitor), T-tap, various male/female connectors(spade, fork, ring, crimp), DPDT switch, electric tape, 2 X diodes (1N4001), 1 x 68uF electrolytic capacitor.




    The two middle prongs on the switch are both connected to ground.

    Nice but I dont see the issue, just open the throttle a tiny bit for 10 seconds and its good to go? Or are people having other issues? My 235cc has always started fine with a touch of throttle (only been down to 32 degrees tho)
