Dim Turn Signals
Posted: Mon Sep 04, 2017 1:53 pm
My turn signals on the bus are too dim and since I pull the juice for our towed from the back of the bus our towed lights are also too dim.
I’ve checked the wires and circuits (I have a wiring diagram in the manual that came with the bus) and it seems that the problem is what they call the “Variable Load Flasher”). I say that because, although I have full battery power 12+ volts going to the above mentioned “Flasher” I only have 3-9 flashing volts coming off the other side with the turn signal switch on.
Then the current goes through a “Relay” switch (one for the right and one for the left). And that’s the same voltage I’m seeing at the turn signal bulbs and the same voltage that is going to my towed lights. Which explains why the lights seem so dim.
So, the first question is:
1. What is a “Variable Load Flasher”? I understand what a “flasher” is, it’s the “Variable Load” part that I don’t understand.
2. Why would you use a “Variable Load Flasher” AND then send that current through a Relay switch? A Relay Switch I understand is used to control a high amp circuit with a low amp switch. The low amp switch would be the turn signal switch on the column.
The Variable Load Flasher seems to be controlling the Relay Switch.
But this arrangement doesn’t seem to be working correctly. Because only 3-9 Volts is getting through the Relay Switch to the turn signal lights (for the bus and the towed). But that’s the same voltage that is coming from the “Variable Load Flasher” so the Relay Switch doesn’t seem to be the problem.
3. Is it normal for there to be such a huge voltage drop through a “Flasher”? Or does that indicate that the “Variable Load Flasher” is worn out?
We need to leave in a couple days so I’m running out of time to solve this problem.
Thanks for your help.
