HOPWOOD MV F41000R MISS.psdata Hi guys. I have an MV that runs rough, like a missfire. I am wondering if you can help me to understand the trace I have taken? The voltage spikes at the end of the burn time and I have not seen this on anything I have tested previously, and looks wrong. Thanks very m...
Hi, The voltages look odd there. Unless its an unusual CAN system (I am also not experienced on 2 wheels) the voltages look really odd 0 to 4V and 1V to 5V. When posting waveforms can you either post the waveform or use the Edit / Copy Entire Waveform As Image command. That allows us to check the s...
Do I check the ECU sensor grounds in the same manner? ie black to groud & red to sesnor ground? What settings do you recommend on scope for these tests? I didn't explain myself all that well previously re the battery voltage reading as expected when ignition truned off. What I was truing to say was ...
Dom It is one thing testing resistance & another load testing ! The grounds you checked check again with the bike running with the scope as a DMM. (black to ground (Batt -)red to ground being tested)) Does the dash receive the voltage from the ECU for the engine via CAN ? Grab a CAN capture anyway ...
Alan, your suggestion of software issue is where I am at with it. The software is in the dash I would expect. If no software in dash then just the dash. I am just wanting to be able to diagnose and not guess. I tested all dash loom wiring voltages and interestingly, left hand switch block function r...
HI Alan, thanks for the speedy reply. I am at home now but can get more data tomorrow. I will upload or PM what little .psdata I have, hopefully it will help. It was batt voltage & current yes. Actual battery voltage when tested at battery is over 14VDC. Yes, dash has displayed voltage and is inaccu...
