Nearly there!!!

So this week has been a week of clearing off the smaller jobs.


  • Plumbing in the cooling system
  • Testing the fan operation
  • Extending the Alternator loom and wiring it in
  • Drilling, tapping and installing the Oil Temp sensor plus wiring in
  • Installing the Oil Pressure sensor
  • Wiring in the Coolant Sensor
  • Fitting Oil Filter & Filling with Oil (Calibrating dip-stick)
  • Filling with Coolant
  • Filling some fuel, Calibrating the manual tank dip-stick, testing the fuel gague in cockpit, testing plumbing, completing electrics for pumps
  • Re-fitting seats


Coolant System
We use a combination of Samco hoses to make the shapes requried to plumb in the coolant system, in the end this was a combination of 90 Degree bends with joiners. This made the closest OEM looking solution. We tested the over-ride switch and and bridged out the otter fan switch and the fan runs fine both times. Looks like the coolant system is all complete.



Fuel System
We ran a heavy duty feed to the rear of the car and decided to use the existing dash mounted switch to power up some relays to act as a local switch for the 3 pumps. We filled the tank one gallon at a time and notched the tank dip-stick each time. This will give a way of accurately managing fuel level given the usual challenges of the Morgan OEM fuel gauge. That said, the fuel sender and the gauge is working fine. Having plumbed and wired everything in we flipped the switch to prime the swirl pot... sorted.. step one completed. Step two, testing the Volvo main pump... well... let's just say it was a little over-powering. The main pump blew the fuel filter apart!! So in the end we reverted to a high flow Facet unit and mounted it recessed where the Volvo unit would have been.. So now.. it's all working.



General Wiring
The alternator wiring was extended from the N/S to the O/S and using the Brise instructions the loom adaptor they provide was spliced together, which means we also now get a battery light on the dash. The horn had to move slightly to the front side of the cross head. We knew the alternator may need some spacing once we had a suitable 5 groove belt and having turned it by hand we found that a slight miss-alignment meant the belt wound itself off. So with an extra washer on the alternator it stayed on ok.. so all set on that front.
The other wiring that needed sorting was the ECU and Telemetary sensors. The Oil Temp (important for racing), Oil Pressure (variable, not 7psi switch) and Coolant Temp. So Friday night we spent most of the night soldering these and splicing them into the relevant looms. Dash, DL1 and Omex.

Next Steps
This morning I trailered the car round to Hayward and Scott to get the exhaust fabricated. There were some other interesting cars already getting sorted out. Anyhow, this week will see the exhaust manifold and side exit system fitted. Which leaves getting the ECU set-up next Monday.

This is handy as the TyCroes final race regs came out today.... We're number 20 and 201.
