No juice to either bulb, fuse checked good and swapped, relay checked good and swapped.... what is next on the agenda for me??
Thanks from Jules, first message from new guy on the block
You ain't kidding. When they rate a bulb for so many hours, you can set your watch by it. When one goes, the other one of the pair is going to fail very soon. When one goes, I replace the pair. The high beams usually don' t get as much use as the low beams so the lows usually fail first. I would still put a meter on tbe bulbs first but the switch is a good possibility.
Assuming your correct and there's no power being supplied to the lamps then I'd suggest doing some tests at the relay before going to the switch. The relay is a lot easier to access than the switch and it's always best to do the easy things first.
Remove the H/LP HI relay form the engine bay fusebox and measure the voltage on each of the terminals on the relay socket in the fusebox. With the ignition on you should have two terminals showing 12V. If that checks out OK, do a relay bypass test by linking the two terminals on the relay socket as shown below. If the bypass test makes the lights switch on you know everything from the relay to the lamps is good and the fault must be either the switch or the wiring between the switch and the relay.
Yeah jumping he contact in the socket is easy. If there was someone else to turn the switch listening for the relay clicking and/or feel it with your finger.
Its quite possible both are burnt out. You know how many people I see driving without a headlight on and they don't know it. They come on with low beams as well. LOL
That is an alert that show be added to the dash for clueless drivers who can even drive at night with nothing on and not realize it!!! You've seen them right.
If he finds the jumper lights up the 'hi' beams, he should try the 'flash to pass' position on the stalk. The 'flash to pass' directly grounds out the relay without using the BCM, whereas the 'hi beam' position on the stalk uses the BCM (via other external influence) to provide the grounding for the relay.
Triplett, US vehicles did have fiber optic wire indicators way back in the mid 20th century on land yachts that indicated when external lamps were actually illuminated. And later replaced by 'lamp out' modules in the hi-series vehicles. I'm sure y'all had them too. I can't understand why the vehicles now days don't have mandatory lamp bulb current draw monitoring devices to alert the driver as you mention; every other situation is monitored (can you say 'seat belt'). Since most US states have done away with the scheduled auto inspection requirement, many things go unnoticed until a regrettable incident. My hat's off to the State of Virginia and their anal inspection criteria. Ahh, I feel better now!
A few vehicle had them here at least a decade ago. But it never caught on as standard feature. Maybe Auto Headlights (No here on the SF STD for some reason) and illumination monitoring should be standard. You can't assume a single light heading toward you is a motorcycle.
Some people just don't care and drive knowingly their lights not working.
Ok I feel better now as well. LOL
