Turn Signals
« on: October 21, 2007, 09:40:27 AM »
New problem. My left turn signal is very lazy. Right one blinks about one time per second. Left one blinks about once every three or four seconds. I've checked inside for corrosion, nothing there and rubbers are good. Electrical is my weakest suit. Anybody got an idea?

Thanks,

Bill

That tells me that you have bulbs on the LEFT side that are under the recommended wattage.  If you have a standard flasher, and the bulbs are low wattage, they will flash slowly.  Check your manual for the proper bulb and wattage for the front and rear turn signals.
OR, you have some corroded or loose connections, maybe the grounds need to be cleaned up, if the bulbs check out.

Thanks Steve,

I've checked the bulbs and they all appear to be correct. This is a single wire system and I suspect that the problem is with the mounting on the left rear unit. It looks like sometime in the past (this old guy had been sitting for 15 years when I bought it) it was dropped (lightly) on the left side. The crash bar saved the front, but the rear light took a hit. It doesn't fit tight and has some movement, i.e loose ground. I'm in the process of taking it down to check it out. If I can't get it straightened out to make a tight fit I may have to replace it.

My 2 cents:
All 1157s are not created equal.  And in fact, an "1157" is not what most of our bikes take.  Honda was very specific in the bulbs chosen for each model(up until the mid to late 70s) because of current output of the generators(or lack thereof).  And yes, the dealers will sell you a Honda bulb at a premium price, but you're getting a better bulb.  The base has nickel in it for better corrosion protection.  The filaments are heavier duty, and in 1 or 2 cases have a "holder" in the middle of the filament, all to help fight against vibration.  Also, the exact current information(either wattage and/or candlepower) is typically engraved in the nickel base, making it easy to verify a match.

Bill,
A quick check is to swap the bulbs. When I swapped mine all my problems went away. I suspect the connector/bulb junctions must line up differently.

OK, interchanged the bulbs. went out for a quick check ride and now nothing blinks. Everything lights up but no blinks. I'm stumped.

Have you tried replacing the flasher unit?  Electronic type?
