Cawthray's Roadster Build

[TomC]

Well safe to say things didn't quite go to plan. We got the wiring all done but no spark haven't had chance to have a proper look over it all yet but reading up it seems quite common so we have a few things to double check. We're using an edis 4 unit with a microsquirt v3 ecu.







Obviously the earths on this pic are just temp.

Well the good news is that we have found out why we don't have a spark, the bad news is the reason we don't have a spark! Turns out our engine was from an automatic so the crank sensor housing is different to the manual. The housing is on the engine behind the flywheel so engine has to come out again
This thread shows the difference better than i can explain. http://www.locostbuilders.co.uk/view...php?tid=182948

How do chaps long time no post. Been busy with the build and finally got her running!

I emailed approvals@vosa.gsi.gov.uk to ask about the possible roll bar problem and this is the response.

Good afternoon Tom,
The reason for the slight confusion here is that the requirements for a
roll bar differ dramatically from that of a seat belt anchorage point. As a
roll bar, the IVA examination simply needs to establish that the bar is
suitably attached to the vehicle structure. However, if you then attach a
seat belt mounting point to a roll bar, it becomes a seat belt anchorage
and is then assessed as such. The main requirement for a seat belt
anchorage is that it can withstand a pulling force in the region of 1.5
tonnes per anchorage. Therefore, this bar will be expected to withstand
more than 3 tonnes of force, as it has two anchorage points fitted.
Obviously, this will require a very substantial mounting arrangement to
acheive that. A very useful guide to seat belt anchorage strength assesment
can be found at Annex 3 in section 19 (Seat Belt Anchorages) of the IVA M1
manual. I have therefore attached a link to the latest version of the guide
below:

IVA MANUALS -

So still not really any clearer i think as long as its solid enough we should be ok also going to make sure we have this email when we go for the test so we can at least say we have looked into it and interpreted it as been ok.

Other than that we've just been plodding on with the electrics.
