IVA

The big test - this replaced the SVA test as a sign of road-worthiness of the car. Tales of the lottery of the IVA made me nervous.

It was done at Leighton Buzzard and the chap who did the test was a really helpful. It's a thorough check which starts with making sure there are no sharp edges using the 100mm ball. Then it's on to a check of the underside and setting of the headlights. The brakes were tested and OK so the speedo needed doing next. Typically, my luck ran out on the one component that wasn't checked on the road test during the PBC. The speedo wasn't working.

Brilliant.

The rest of the check was fine and despite the speedo, there were one or two easy things to fix but we needed to check the speed sensor we'd replaced after the failure in the PBC. When I went to start the car, the ignition fuse blew as it had with Caterham.

In a nutshell, I have a problem around the wiring associated with the speed sensor/speedo. If I disconnect the speed sensor, the car starts but when it starts with the speedo sensor fitted (assuming the ignition fuse doesn't blow) the speedo doesn't work.

It'll be dropped off with Caterham next week to replace the diff and check the speedo...
