Not a newbie bit lost all my login info...
Has anyone tested a Bongo clock spring? My airbag light is on and I have removed the clock spring unit - need to know if the two airbag wires should be separately wired? Both my wires are showing a connection to each other - I would thought this is a short?
Any info would be welcome before I shell 140quid on a new one!
Cheers chaps

Re: Airbags and clock springs
The resistance between the wires into the air bag is quite low as its a simple detonator construction, normally around 5-7Ω lots of meters won't show that accurately.
Resistance between the wires in the clock spring itself should be basically infinite!
Just how and where are you actually measuring the resistance ?

Cheers Geoff,
I was basically checking continuity of the clock spring and was surprised to see a connection between the two airbag wires with the spring completely removed from the loom?

Re: Airbags and clock springs
Continued investigation..
Clock spring has perfect continuity, after I disarmed the shorting pins in the connector block.
Airbag has continuity, although reads 2.3ohms - is this correct anybody??
Dash light remains on, even when airbag connected direct to loom ( bypassing clock spring)
My question to the panel is: do I buy a new airbag or can I disable the lamp(!)

Re: Airbags and clock springs
Yes 2.3Ω is fine, the light is controlled by the computer mounted down in front of the gear selector under the dashboard, it should be flashing a coded pattern, but may depend on what age of vehicle use this page to identify http://www.philmcfadden.co.uk/MazdaDiagnosticBox.htm
Re: Airbags and clock springs
You should never use an ohmmeter on an airbag
You should never measure the resistance of an airbag unit or probe an ohmmeter into airbag wiring unless you know exactly what you are probing/airbag is unplugged. Ohmmeters use a very small current to measure the resistance which could be enough to detonate the airbag.SneakyPete wrote:Continued investigation..
