Hello, I bought a GPZ 1000 RX Bj. 1987 with 52tkm. It stood for 8 years and was switched off due to ignition problems. The problem: If the ignition is switched on, 12V onboard voltage should be on the inputs of the two ignition coils. But it is not. With one ignition coil there are 11.3 volts on and with the other 0.1 volts. Here is a list of what I have already done, but did not help: – other used CDI built in (but still 11.3 and 0.1 volts on the coils) – with The key in the ignition lock is waved around (no change) – Kill switch checked (with OFF the voltage on the coils drops to 0 volts, i.e. is i.o.) – Side stand switch (lamp in the cockpit goes on when the stand is folded out. Switches also measured with Ohmmeter. Is therefore measured – clutch switch – also works. – all fuses visually checked and additionally measured with Ohmmeter. All are measured – the three diodes in the fuse box. All i.o. – the Kab el measured from the CDI to the two ignition coils. All have 1.0 -1.5 ohms. So also i.o. – wobbled on all cables and the main wiring harness. No change. – checked all plug connections. Without success. – neutral switch checked. Lamp in the cockpit goes on at inserted idle. So i.o. – in the fuse skate are three relays (blinker, starter and main relays). The main relay is warm with switched on ignition. Starter and main relays measured. Both show the same value. e an. So I don’t know what else to do ? Maybe both CDIs are defective or they are both OK. Unfortunately, you can’t measure the CDIs with a normal multimeter. I still noticed that when the ignition is switched on, there is no voltage on the fuses in the fuse box. But horn, light and starter work. Is there only voltage when the motor is running ? The voltages of 11.3 volts and 0.1 volts on the ignition coils are a big mystery. usually 12 – 12.5 volts. Does anyone have an idea ? I can’t remember anything anymore ! Thank you and nice greeting, 2taktpower
