Update for anyone still with me on this.
checked the pulse generators resistance as per manual and they are within spec. 208 ohm for front, 211 for rear.
Checked coils: resistance across the two terminals is 0.4 ohm front coil, 0.3 ohm rear coil. Slightly above manual specs but they both will send spark when hooked up to front cylinder wiring. Green terminal to plug cap resistance is 7.98 kohms rear, 9.24 kohms front, again within spec.
checked continuity of all wires from the 4 pin and 16 pin plugs from ECU to the female terminals that attach to the coil terminals. Zero ohms resistance for the green/white, black/blue and black/yellow wires. All pins in the plugs are in place and wires look secure.
One thing that seems strange is that i get zero or very low voltage when 1 probe in the green/white wire terminals and other to ground with ignition on. I get 0.18 amps at the green/white terminals and 0.25 at the black/blue and black/yellow wire terminals when connecting those terminals to ground with the probes.
|I have not done the max voltage tests of the coils and pulse generators as per the manual supplement for the R5K because i don't have a peak voltage adaptor. Is is worthwhile?
To recap: bike started and seemed to run fine on stand, except that RC circuit was burned out. Removed ECU and sent to 2TRacelab for repair of RC circuit and total refurbishment. After repair was tested by Nick and said to be in perfect working order. Reinstalled and bike won't start. Have good spark at front cylinder, rear sparks but only on rare occasions. Same result when front and rear coils are switched so coils must be OK.
I could do voltage in and out tests on ECU but i know there is voltage in and out because i get spark at front cylinder and can see the temp needle move slightly when ignition turned on.
Is it possible there is a problem with the ECU? wish i had a known good PGM II to swap just to see. Anyone got one to sell or loan ?
I feel this has got to be a problem with the circuit related to the green/white or black/blue wires to the rear coil. The wires themselves seem to be fine, so is there a way to test that circuit at the ECU?
