Noticed the alert on ERA's Owners Private Downloads page about some bad headlight dimmer relays getting out. I don't seem to be having the exact issues mentioned in the alert but I haven't used my headlights much. I will turn the HL on and run through a few dimmer/high beam signals and see if anything shows up.
Also found the test procedure for the turn signal switch but as long as the HL dimmer lead to the switch is disconnected it works OK. I think that probably points to the dimmer power shorting to the left turn signal lead - maybe?
Apparently power is flowing from the HL dimmer relay to the dimmer switch or it wouldn't be shorting the turn signal. I guess that would be the main test that it's working. However, should it be sending power to the switch if the headlihghts are off?
