Banks Turbo Install - Turbo and Pressure Chamber Not Lining Up
Oh, THAT brace.. Yeah, mine was quite tight, barely got it on; it was a struggle. I may have taken a rat tail file or dremel to its hole to finally get it on; not sure, but I remember it was a PITA. I hope you enjoy the end result as much as I have enjoyed mine. Trouble is, I tend to burn more...- Lawrence Koepke

Banks Turbo Install - Turbo and Pressure Chamber Not Lining Up
Which tranny? I have the E4OD, custom built for me at Geezers Garage in Oregon, and the brace lined up perfectly. Regarding the firewall "modification", IMHO, they have us cut much more than needed out, but, yes, the downpipe needs all the clearance possible, but the driver's side didn't need so...- Lawrence Koepke

Banks Turbo Install - Turbo and Pressure Chamber Not Lining Up
I installed the Sidewinder kit in my '91 F350 last year. After MANY struggles like yours, I finally ended up grinding the support foot on the casting, trying the fit, then grinding a little more, etc. until I finally got the casting installed. Maybe the '91 year is somewhat different than the...- Lawrence Koepke

7.3 idi turbo whistle
Where is the whistle coming from? I installed a Banks Sidewinder kit on my '91 F350 7.3 IDI, and hear a whistle in the exhaust at idle, but that's all. The Sidewinder produces zero boost at idle, as designed.- Lawrence Koepke

Glow plug troubles
The glow plug controller 12 V source goes through a big connector in the harness near the passenger side head, and is protected with fusible links buried in the harness next to the passenger-side battery. The pins in mine developed corrosion, creating resistance. My short term fix was to add...- Lawrence Koepke

Glow plug troubles
Another vote for wires. The glow plug controller wires and the connector buried in the harness have caused many an IDI to fail to start as they age. I have a 1991 F350 Lariat Crew Cab, and I found high resistance in the connector that is in the middle of the harness, feeding voltage to the...- Lawrence Koepke

Ignition Switch RUN terminal wire R/LG always hot
Well, I just opened up my harness, pulled out the unused glow plug wires to the old relay location, anf found to my delight that the ignition RUN wire and Warning light wire are just the right length to reach the new location on the passenger fender plate. So, maybe I should consider pulling...- Lawrence Koepke

Ignition Switch RUN terminal wire R/LG always hot
I've been doing some number crunching on the glow plug wires. I had 2 factory 10 gauge wires with 14 Gauge fusible links in them. A 14 gauge fusible link is rated at 32 amps, so that suggests to me that a total of 64 amps is the maximum the factory wiring can handle, much less than what I have...- Lawrence Koepke

Ignition Switch RUN terminal wire R/LG always hot
I have performed a GlowPlugWire-ectomy in prep for moving the relay onto the passenger fender. The plan is the use 4 AWG wire to and from the relay, one cable only to the rear of the engine, tied to the glow plug wires. I've read the glow plugs can draw 200 amps, and Philip1 (above) ended up...- Lawrence Koepke

Ignition Switch RUN terminal wire R/LG always hot
Ah, that clears up a mystery, as to why on the back of the manifold. My experience tells me that items are mounted on the manifold for either vacuum or coolant. I gather it's still there on the 7.3 because "that's the way we've always done it", and "that's where the mounting holes are". Wow. Two...- Lawrence Koepke

Ignition Switch RUN terminal wire R/LG always hot
laserjack, I see you have the Banks turbo. I received mine on Friday, and it will be the next project after I take care of this current issue. I'm wondering if I should move my relay/controller like you did. I have not seen one of these trucks with the Banks Sidewinder installed, but I have to...- Lawrence Koepke

Ignition Switch RUN terminal wire R/LG always hot
I have read that the glow plugs can draw up to 200 amps, but laserjack suggests a 150 or 175 amp fuse will suffice. I'm thinking he may know from experience. How many amps do the glow plugs draw? I'd test the draw at my relay, but it's dead. I'm heading to the parts store to get a new relay, and...- Lawrence Koepke

Ignition Switch RUN terminal wire R/LG always hot
Thanks for the tips. BTW, I had replaced those glow plug relay feed wires so many years ago, I had pretty well forgotten about it. I'm wondering what to replace them with so I don't go through this again. I thought AWG 10 automotive wire would be sufficient. Do others have this problem with...- Lawrence Koepke

Ignition Switch RUN terminal wire R/LG always hot
To all who posted, a big hearty Thank You! I finally found the culprit, in the harness right where Franklin2 suggested. One of the glow plug wires feeding the relay had gotten hot enough to melt insulation on itself and a blue wire next to it, and I suspect the blue wire is the FSS solenoid...- Lawrence Koepke

Ignition Switch RUN terminal wire R/LG always hot
I replaced the switch down toward the bottom of the steering column, but I have never tried it, because the R/LG wire (RUN) should not have 12 volts on it when the connector is not connected to the ignition switch. The wire next to it, BR/PNK (I think), is also sitting at 12 volts- Lawrence Koepke
