[QUOTE="dcarver, post: 981829, member: 956"] [URL="https://candybuttorg.ipage.com/cba/comment/401#comment-401"]Did some troubleshooting last night and took video of testing results..[/URL] [URL="https://candybuttorg.ipage.com/cba/comment/402#comment-402"]And here are those results in a table. Not sure what all this means yet, as in what values are acceptable or not..[/URL] [I](apologies for sending you off to the CandyButtAssociation site, but I can't get tables to post nicely here..)[/I] Some observations: [LIST=1][*] [*]Voltage output is higher at idle than at 5k rpm. I would have thought output should rise with rpm? [*]I have 0.7 to 0.9 ohms resistance from RR output, red wire, and power fuse hot side. Meter lead resistance compensated - .9 ohms sounds kind of high, not sure though. [*]Voltage drop between RR output and battery terminals is less essentially zero with key off. [*]Voltage drop between RR output and battery terminals is 0.4 vdc when key is on, engine off. [*]Voltage drop between RR output and battery terminals varies from 0.6 to 0.9 Vdc, engine and fans running. [*]RR current output is ~25 amps, with greatest output at idle. [/LIST] Has anyone else noticed greater output at idle rather than 5k rpm? [/QUOTE]
