Indicator Problems - Derbi Senda R 50

[truslack]

The other day my indicators suddenly packed up without warning. I WD40'd the the connections thinking it was just water in the sockets and still nothing.

Apparently on the Senda it is the regulator that controls the flash so I traced the wires from that and cleaned them with White Spirits. I now have the indicator dash light coming on for one side of the bike (left) but still nothing on the right. I have disconnected all the indicators, but if I connect them the dash light stops flashing even though the multimeter shows the pulsing 11v through the wires.

Any idea why giving it a load would stop it? And how to get the right indicators working?


Thanks
Mark

What are they led indicators or bulbs ?


I can't see how a regulator on its own controls the flash rate ? are you sure theres no indicator relay ?

[truslack]

They're bulb indicators. The Regulator is more like a multi unit, 3 live wires going in and 3 earths.

In the spare parts catalogue it is labelled as:

REGULATOR RECTIFIER / FLASH UNIT 00H01004841

Pre 2003 Senda's used separate flasher unit and regulator, Derbi decided to change this and mine was the first model to have the combined unit.

Thanks

Happened to me the other day and caused profuse swearing.

Picture the scene:

Front left: working
Rear left: working
Front right: working
Rear right: god knows why it wouldn't work (long story)

I managed to fall over at a junction and smashed the front right indicator. I now have no indicators on the right hand side. The green light on the dash would flash fast on the right and when indicating to the left the light wouldn't flash but the indicators were working fine?

I replaced the smashed front indicator and the green light flashed fast when turning right as the rear right was still not working, but now when turning left the green light flashed normally again?

After a long and hard battle to get the rear indicators working fine the green light would flash correctly and slowly.

Why have the green light working intermittently when more both indicators are out on one side is a mystery to me.

Just follow the wires and ensure that the connections are correct and solid.

Check your earths from the bulb holders to ground. It's no good having voltage on one side if there is no-where for it to go.

I've taken 2 of the wires off the regulator/flasher unit and connected them to the old 2 prong flasher unit from my RS50 and it works fine, there's just a bit of a delay.

Looks like I need to buy a new reg

Thanks for all your help, it is much appreciated.

Sendas have always had the indicator relays built into the regulator assy, and yes they are known for failing as the regulator can get quite hot as it looses the excess voltage from the stator.

Old sendas upto Oct 2003 have a unit with all the wires in a line.

New sendas Oct 2003 onwards have them 3 up, 3 down in a block.

The ones all in a line are the most problamatic, but saying that the new style ones are still occasionally packing up.
