Project Custom Motobricks / Re: 1992 K100RS 4v abs (no cat) No spark or fuel feed after rebuild.
« Last post by Jhullmoto on Today at 05:23:11 AM »After reading the manual from Laitch (thanks, that’s an awesome resource) I have got a very small output on both the 2 motronic outputs to the ignition amp. Only a fluctuating 0.20v on both during cranking. One is black (sw) on pin 2 of the amp connector and one is black/white (sw/ws) on pin 7 of the amp connector. The manual states that it’s a low voltage but does not say the exact expected parameters.
I am picking up a replacement hall sensor today just in case that’s the problem. I’ll keep you updated.
I should quickly add a side note; this is the 2.1 motronic and as such (I think) has no CO sensor. There is a lot of discussion regarding the Co sensor but there was visibly no sign of one on the bike’s exhaust system nor is there a connector for it on the engine loom. I think I’m right in thinking that the 2.1 doesn’t utilise this and has only the potentiometer. The manual seems to confirm this in a roundabout way but confirmation would be good.
Also, and I’m just shooting from the hip here but the only wire out of the engine loom I haven’t resolved is the brown/white (br/ws) from the diag plug to the deleted abs control unit. Does this perhaps need a resolution? This is the only abs related wire coming from the engine loom.
Thanks again.
