Reply to "Maui garage find Intermeccanica rebuild"

Other than disassembling the house of tarp, I've been working in air conditioned comfort for the last couple of weeks. Lots of time setting up the plumbing for the fuel system and the air conditioning. Lots of time fitting and modifying the "new" 15 year old wiring harness that the PO had Henry build for him. 


Lots of time setting up 2 additional fuse/relay area (one in the repurposed battery box and one on the engine firewall).  Then just hours and hours of crimping, soldering and heat shrink, cutting some things back out and getting it right the second time.

Oh yeah, I've got a battery cutoff switch and some honking big primary, ground wires and grounding buss.


Small fuse and relay area on the side of the AC box (old battery box). These feed the fuel pump, driving lights, windshield washer and +Vs for the radio and phone chargers. You can see the other side of the battery cutoff switch (sans key) on the right. Spare wires from the engine area and the cabin are stored below the relays.


Battery box with the AC evaporator installed. Blower hoses run from here into the dash and footwells. Windshield washer filler neck can be seen on the passenger side of box. The bag and pump are attached on the other side in the wheel well.


The rear wiring is complete, the dash is 85% the front end is complete, but my parking lights pulse in time with the fuel pump. I'm going to see if adding an additional ground wire improves the brightness. Everything but the alternator light is an LED so things should be pretty darn bright.

Fuse/relay box for Speeduino, coils, AC condenser fan, AC clutch and oil cooler fan is in upper left corner. Circuit breaker on feed from the alternator is on bottom right, below the Speeduino box.



Nearly done with the dash. I'll add the gauge trim rings at the end.


Driving lights automatically come on when ignition is on and switch off if just the ACC switch is on. Battery is tucked way up in the nose.


My biggest sticking point was the flasher relay. Totally unresponsive and then it popped a 15 amp fuse. At first I suspected the new fangled LED flasher relay, but it turned out to be a miss-wired relay socket. I'd complain to Henry, but I suspect that the tech who built the harness 15 years ago may have escaped justice. Fortunately, once I got the socket straight, turn signals and emergency flashers worked fine.

I had a stupifying experience trying to get the horn wiring set up. Turned out that even a shiny copper tab on the steering column won't conduct if the tab rivets and column underneath the rivets are corroded. Oh yeah, 14 years sitting outside on the edge of the beach... I just drilled a new tab mount and stuck a self-tapping stainless screw in it. Beep beep! 

Finishing up the radio box which also houses my fast phone charger, USB charger, AC cabin temperature switch and the circuit that flips on the 'low gas' light when there's two gallons of gas left in the tank. Oh, and it also has a $10 radio. That'll be finished tomorrow and then I'll start on the doors, mirrors, decklid and windshield.

The car started from turning a key in the dashboard switch for the first time in over 15 years. I know I'm getting excited! PS, Marianne is pretty happy that the house of tarp is just a fond memory. We're now having a conversation about when the grass will be back..
