Horn honks when hooking up to battery

So, I apparently need high caliber brains to fix this. I went to put the steering wheel back on, after trying to clock it, and I noticed that the steering wheel was on upside down, but because the wheels were turned slightly out. So I started the truck, straightened them all without incident except then the horn would not blow. So I pulled the steering wheel off, removed the locking plate and made sure the cancelling cam was seated correctly. Put everything back together and when I went to hook the battery back up, the horn blew. So AGAIN broke it down to the cancelling cam, AGAIN the horn blew. So I decided to try just putting the cancelling cam and locking plate back in place - and the horn blows. WTH!!! it wasn't doing that when I started it to straighten the wheels. Any thoughts or ideas. Prior to this the horn was fine. I was watching some videos and I will check the horn spring and fuse today. I also have all the parts ready to order in my cart from where I have ordered parts from.

Motor Mounts

March 10, 2026, 12:02:18 am by roger97338 | Views: 5072 | Comments: 2

I have a broken motor mount I need to replace, on the passenger side. The bolt that holds the two pieces of the motor mount assembly is absent. I'm just assuming the rubber part of the mount has been damaged by a broken bolt wobbling around in it for who knows how long.

Last time I replaced motor mounts, the engine was out of the vehicle. Easy peasy. Not so this time. Now I have all the things in my way.

So I'm looking for advice. Things I should do. Things I absolutely should NOT do.

Any input is appreciated.

75 Chevy 2wd; 350/TH400; lowered 3/4; headers; no a/c; not sure what else you might need to know.

Why doesn't fuel flow from the tank?

March 09, 2026, 08:39:30 pm by fiddler | Views: 6857 | Comments: 2

I have a titled 1974 Chevy c10 stepside. I say titled because it has so many replacement junkyard parts on it. I think the engine is from a 1976. Anyway, it had an intermittent fuel starvation problem so rather than fool with it I just pointed the parts cannon at it and replaced all of the filters and the fuel pump. In the process I prepared to plug the input to the fuel pump when I removed the hose. But no fuel came out. I put some air pressure on the top of the tank, and fuel comes out of the fuel line, but it doesn't free flow. Appears not to be an issue, but can anybody tell me why that is? Thinking maybe some kind of fuel line routing or special valve? Oh the intermittent appears to be solved, but... it's an intermittent so it's going to take a few days to call it fixed....

Transmission dip stick

March 08, 2026, 02:53:32 pm by fiddler | Views: 4234 | Comments: 2

I have a titled 1974 Chevy c10 stepside. I say titled because it has so many replacement junkyard parts on it. I think the engine is from a 1976. So the cap is no longer on the top of the transmission dip stick and i can't tell how to get a replacement dipstick or how far to insert for a level measurement. Can anybody out there tell me how to measure a dipstick for length? From the tip to the cap? Or tip to bottom of the finger loop, or maybe the top of the finger loop? The transmission is a th350 as identified by pan bolt pattern. The engine is a 350. The instrument cluster is from a 76 I think and uses a voltmeter instead of an ammeter for battery charging indication. Could be that the dipstick for any year 350s setup could work. Anybody know?? Thanks in advance

TH350C orange test connector use?

Hi all

I'm trying to get my lockup working on my TH350C to squeeze every bit of mpg out of the old Scottsdale

I want to know what kind of behavior I should be seeing on the orange connector:

- 12v when the clutch should be engaging?
- 12v only when the clutch is engaged?

Thanks?
