Having recently had to rescue SWMBO from her car park at work with a flat battery for the 5th time, decided something had to be done.

Pop up headlights are all well and good, but if you don't turn off the sidelights you go flat by the end of the working day. The Eunos (MX5 Mk1) doesn't come with a buzzer/chime, but you can fit one by wiring up a buzzer to the engine fuse and the sidelights fuse. Fortunately, these are next to each other in the drivers footwell. The buzzer was stolen from a soil moisture testing gizmo made by my son at school several years ago (bad dad!) but can be had for £2 from Maplins. Simply stick the wires into the fuseholders.

Now when engine is on, no buzzing, as soon as engine is turned off buzz buzz buzz.

One of the simpler mods I have done on any car

My dad had one of those buzzers retrofitted to his Cortina!

I remember those buzzers, I used them for a school project too.

Sadly the following day the battery went flat again (dead flat - nothing/nada) so had to eat humble pie with SWMBO having blamed her for leaving the lights on. Possibly a problem with the light/indicator stalk, which I have read won't draw current when in the full beam position. Trying that now. Problem is it doesn't happen every day, just now and then... .

If it doesn't happen every day, I'd be looking at contact switches on doors, boot etc. Basically, any contacts that may be prone to damage from movement. Researching my first Range Rover purchase
