    Hi - At idle: Left or right indicators on: Amps read +10 normally - flashers working as advertised. Switch on low beams and amps go to zero w/ affect on indicators, switch on high beams and they go to -10? with greater affect on indicators. Affects = slower & weaker flash on L/R indicators. Any insights/recommendations? Thanks,

    What is your idle RPM? (1000 RPM would be better than 900 RPM for this issue)

    What is the voltage at the battery at this RPM? (You might try measuring this with: A. everything off, B. turn signals on, C. turn signals and low beams on, D. turn signals and high beams on.)

    Do you still have the stock 115A alternator? (That is a huge alternator for the era.)

    Have you headlight bulbs been "upgraded" or are they still stock?
