BEC electrics expert needed!

Hi guys

I have busa loom apart here and and trying to sort it for car use and I have a few questions.

1. Why dothey use a diode switch on the side stand and how do I wire it out.

2. Why are there three wires on the tilt sensor and again how do I wire that out?

3 What else will I need to know as I get a bit further in..

Thanks
Jason

The diode is there to provide the "OR" function, as in...

Start the engine if the gearbox is in neutral OR the clutch is in and the side stand is on.

You will need a resistor in the circuit where the ignition barrel is...anti theft device - stops it being hotwired. 100K ohms i think...

You can simply join the Side Stand wires together, that way the "stand" will always be "up" and therefore you can start the Car in gear!

As Rich says you will need the resistor in the Ign circuit. Let me know if you don't have one and I'll stick one in the post for you!

Do you still have the Tilt Sensor???

What else? err err...

Hi Mate

this is a later one so its got an immobiliser so theres no resistor in mine. ( I checked after reading one of your posts on another thread
)

still trying to get my head around why the button has a diode built in. But I will join it togeather if that works.

Yes I have the tilt sensor but I want to simplifie it take it out the loom completely so I'm trying and avoid squeezing some gunge in it if I can.

The older ones in the haynes mauals have only two wires and I'm wondering if it latches and maybe needs the igniton cycling to reset it??

Thanks for the offer of the resistor but it don't have one as for as I can tell. (after measuring across the ignition switch)

the 3 wire tip sensors are resistor ladders, i haven't got to it yet but i will be removing mine soon, basically i wire is ground, one is supply from ecu and one is return to ecu

you need to resistors, one from supply to return then another from return to ground, the to ground has to be higher that the first but you need to use correct ratios to prevent ecu going up in smoke, best thing is to measure it on the sensor then duplicate it with resistors.

Ive measured it. there is resistance across all three terminals.There seems to be a hall effect sensor and a megnet swinging above.

I think the best thing is to get the car running and then play around with it.


Thanks for the help
