Bongo Fury

I posted a link to his site a couple of months back in response to a similar thread. I did some trialling work with Dave on the original Townace alarm.

Ah, missed that. D'ya think he'd consider Bongoing?

The best route to a solution is if someone can lend me a temp gauge instrument and a sender unit from the head to measure their characteristics.

The next option would be to identify a co-operative owner who lives near me in West Sussex and who knows how to access the back of the instrument panel.

I could then build a prototype for anyone to test provided they can find where to connect it - anyone got a photo of the back of that part of the instrument panel?

How many versions of the Bongo are there to solve?

Voila Dave:

oh btw Dave, the grey wire coming out of the back of the panel is non-standard, this runs to the LED retrofitted next to the temp guage as part of the famous 'Callow' coolant loss alarm

Are these three screws the terminals for the temp gauge?

Someone will need to identify which is V+, which is 0V, and which is the junction of the sender and the instrument - which in a Toyota would be marked "TU" for Temperature Unit.

These wax thingy's that melt at 110 oC are a bit of a cop out for the reconditioners. When testing the coolant alarm I had my engine up to 120oC and although I wouldn't recommend it , no harm was done. If mine had been a recon engine and in 6 months time there was a warranty problem with it they would have pointed to the wax thingy's and said NO WAY. 110oC is not a difficult temp to get a bongo up to and no harm is done.

please take a look at new sensor from Australia just posted many thanks Rich

the left hand screw is marked t-u the top ign and the bottom one e

So this (pic below) is how you would connect the three wires to fit a Mason Alarm.

I can supply ONE prototype with some extra internal adjustments for some brave Bongo owner to buy (£27, same as for Aces and Estimas) and connect to the back of your instrument panel, and then I'll provide advice about how to adjust it based on what results you get. If we can't make it work, return it and I'lll refund what you paid. Assuming it works I can then make a Bongo version based on what is learned from the prototype.

PM me if you're interested, but ideally the prototype goes to someone who has already used a Mason alarm in an Ace or an Estima - you'll know what performance to expect.

Hello Dave fancy meeting you here. In the interest of science and the general advancement of the cause, I guess that guinea pig has to be me then. I'll pm you.

Oooooh - just returned from 2 wks brilliant weather and Bongoing in North Norfolk to read this. Great news that the inventor has been in touch. Good luck Ian, keep us posted.

Paul's already offered to do the testing so we will see how he gets on.

Ah ha, so that's what his PM was about (should have guessed really but being Irish etc......). Well, good luck Paul then
