Default Indicator buzzer

Hi New to the forum. I followed Chris Gibbs instructions on how to install an audible buzzer using bits from Maplins and have been very pleased however I recently noticed that when I have my lights on the buzzer noise is quieter and 'croaky' Any ideas please.

A big welcome to the forum.

I am no electrical whiz kid. Have you by any chance used the lighting circit for the live feed for the buzzer ?

This may account for the poor performance when the lights are on.

If all was well when you first fitted it, perhaps you have a faulty earth connection.

Where electronics are involved, some components are very sensitive to voltage fluctuations. They will work fine for a while then start to fail.

Have you fitted a voltage regulator in your buzzer unit ?

When you have your lights on your alternator will be kicking out between 14 - 15 volts. It may be too much for some electronics and will need to be regulated.

That's about all my pea brain can think of.

Hi and welcome to the forum.
Think Ronnie has hit the perveriable nail on the head, I think I woulld try the earth first cause it's the easiest if that dosn't work try a tempary live feed to see if that does the trick.

Question Indicator buzzer

I have had a re-read of the post that Chris made on the subject of buzzers.

Live feed is from the indicator live wires.

The fault is likey to be either a bad earth or an electronics fault.

Perhaps the most simple way to install a buzzer is to fit a buzzer that is normally fitted to a car towbar Wiring.

A legal requirement for towing a caravan if memory serves me right.

You can find them at most breaker yards for pennies. I don't think they are very expensive new.
