I mod a list for G/S bikes (monolevergs on Yahoo) and this question came in. I don't have an Omega, but maybe someone can e-mail Svante and/or post a diagnosis here? Thanks, K Got the Omega 400W alternator with replacement diode board installed on my '96 GS Basic, and has been very pleased with the performance for some 10K miles. But this autumn the charge indicator bulb began to intermittently refuse to turn off, but stayed glowing partially even at full revs. And finally never turned off completely. I thought it had to do with my clock sometimes refusing to work, but after fixing the clock (found a loose, tiny bulb inside the housing, intermittently short-curcuiting the connection) the indicator bulb still stays on partially glowing. Voltage is correct (have also checked with another regulator installed). Regarding the diode plate I found the checking procedure described in "Classic boxer charging" a little confusing. Measure gives correct readings between AC input terminals and the D+ terminal, and also from all the G connections but there is no B+ assigned. I choosed the connector for the red wire to the starter engine (B+ on the Thunderchild board) and then I get bad results, with big resistance results in both directions for all the AC input terminals. U = 3 vs 1,1 MOhms V = 5 vs 1 MOhms Y = 7,5 vs 0,8 MOhms W = 15 vs 0,7 MOhms This seems a little odd, are really all four diodes fried? Giving no more noticeable sign then a glowing charging lamp?Or is there something wrong with checking the board this way? Has anyone information about the correct checking procedure and results for the Omega diode board? Of course I will also appreciate information about any specific problems noticed with the Omega charging set up so far.
