HELP re Haydn's low coolant alarm wiring!

[windywatson]

Fitted Haydens alarms to both of my Bongos without any problems locating switched lives as sure that Hayden had given addition wiring instructions detailing wiring locations for bongos. Plus a scotch lock to use to conect to the switched live behind fuse box.

Cheers

Brilliant. Thanks.
Located live feeds using Fuse Box fact sheet and tested so know exactly what I'm aiming for.
.... and today its hissing down. the project schedule says complete LCA and LB

I personally am not keen on using scotch locks. We provide crimp connectors in the kits.....better to cut the pos supply wire and use the blue crimp to join in the alarm pos wire....

In the end no scotchloks - I ran a "power lead" from the back of the instrument panel and connected it to the leads on the LCA unit. That way the instrument panel can still be removed without uncrewing my connections on its back. I had the right connectors in my toolkit to do it, which helped. Though I wish I had thought of cutting the wire at the back of the fuse block and using crimp connections to make good!
Oh well, its in and working now. And so is the Leisure Battery split charger, yippee.

Just found the reason for my LCA working only intermittently, (self test function).

It was the bliddy scotch clip.
The LCA wire had been coupled to one much thinner and was making very little contact with its core, probably due to the insulation on the alarm wire being so thick.

I removed the scotch clip, bared back about 10mm insulation on the LCA wire and fitted a new scotch lock, (my stock of bullet connectors are blue, too big, proper Jap ones ordered ).

All is well, 6 tests done before and after refitting glove box

Glad you are sorted. I recall from long time ago that one of the concerns with scotch loks was that they lost connectivity with corrosion. Maybe that was the reason for Haydn's caution. I'm intrigued by your need to remove the glove box. I guess you have routed the wiring from the expansion tank in the cabin instead of under the bonnet?

That's the way the converters routed the wiring. Certainly made access easy, but wiring loom needs to be carefully fixed to avoid fouling glovebox.

Theres a large steel tube running in parallel to the dashboard which is ideal for cable tying the wiring to.

Back to square 1

Finished off yesterday with 3 good tests before refitting glove box, then 3 after, all fine.

Setting off for underseal estimate this afternoon, no test audible or lamp, bngger!

Got back and opened it all up, no obvious dodgy connection.

Planning a re-instal without scotchloks!

[clutha]

Well the saga is over.

The alarm had died!
Whether this was due to intermittent dodgy connections we will never know, but Jo at Hadyn sent me a replacement as soon as I sent the dodgy one back.

I was going the try and rewire via fuse box but found that too tight to get into for my flexibility

A wee bonus was finding a double socket on the radio feed with only one used, so that's my new 12v source, coming live with ignition.

All connected up and working fine

Scotch lok had cut the wire causing a intermittent fault......alarm itself was o.k.

One of the many reasons not to use Scotchloks. The blade inside is designed to CUT into the wires, supposedly without severing them. My auto electrician won't countenance the things

[g8dhe]

They do work and can work quite well BUT ( and its a big BUT) you have to use the correct size wires to fit and that isn't so easy to judge
as there are more wire sizes than scotchlock sizes, plus telling what size wire it is on an existing installation where you don't know the insulation thickness means its a bit hit and miss
