 |

All,
I started the Rotax 582 for the first time today, and everything
was fine but the tachometer and the charging. I'd like some help
de-bugging, if I may.
Configuration: Rotax 582 grey head w/ 3-phase regulator wired per Z-17. GRT
EIS tach wire connected to yellow alternator output wire.
First start: Tachometer reads 0. No variation in voltage switching
alternator in or out, regardless of RPM. Voltage about 12.9V.
Disconnect regulator from alternator. Measure ACV across alternator and get
Rotax spec values. (~14 - 55 VAC depending on RPM.)
Re-connect regulator input wires and disconnect output wire and measure
voltage between it and ground: ~5 VDC invariant with RPM. Note that the EIS
RPM is now working.
Re-connect the output wire and clip DC volt meter between the regulator
output and ground: ~ 14.1 VDC at idle, decreasing to about 5 VDC at higher
RPM. EIS RPM is 0 again.
Basically I'm clueless as to how to diagnose whether the charging
system is working beyond the alternator output. Any help would be
appreciated. I think whatever's influencing the charging is probably
inhibiting the EIS RPM input, as well.
Thanks,
Guy Buchanan
