Ok so I have the dreaded hot start problem. My car is a 95 Griffith 500 fitted with the Foxguard alarm system.

I have seen lots of info online relating to the Meta alarm and hot start problems but not the Foxguard.

What should I do? Is the hot start kit a genuine solution or does it just force the problem to another area of wiring or fix it with no guarantee its permanent? Lots of conflicting info online.

Might be worth checking/cleaning starter motor connections first?

Hi,

I have a 94 Griffith with a Foxguard alarm, and unlike the meta alarm was correctly wired by TVR. I to have suffered from hot start issue (but only when the rad fans were running). Best thing is to fit a starter motor relay into the circuit, I installed one behind the dash, interrupting the ignition switch/starter solenoid wire after the alarm unit. The Modwise hot start kit is only suitable for later model cars as the earlier TVR looms are slightly different and do not have the appropriate cut in points. Definately agree about checking starter motor connections as they can corrode and become loose. Also the starter motors do tend to suffer more due to heat soak, I have had to replace/overhaul both starters on the two TVRs I've owned.

Sorry for being a bit clueless but what would the starter motor relay do? How does it help the cars hot start problem?

A starter relay allows full battery power direct to the starter solenoid rather than having to run through the ignition switch, alarm unit and all other connectors causing voltage drop and ultimately can lead to burnt out ignition and alarm contacts.
There are lots of threads on the hot start subject in PH, worth a read.

I have a '95 Griff 500 that was suffering from the hot start issues. I was down with Joolz a while ago having it mapped and I mentioned it to him. He drew me a diagram of how to make my own hot start kit for the price of some wire, an inline fuse, and a relay ( http://www.ebay.co.uk/itm/Small-4-PIN-MICRO-MINI-R... ).



I used 17 amp wire and positioned the relay on the bulkhead using one of the bonnet catch bolts. I made up the respective lengths of wire with connectors and then bound them together with black tape so they looked like a normal piece of loom.



This has cured my hot start problem.

P.S. I know some people will say that this isn't addressing the core issue but it solved my problem that the car wouldn't start when it was hot and that's good enough for me - especially when it cost less than a fiver.

P.P.S. If you're doing this, don't forget to disconnect the battery before you start.

P.P.P.S. Having said I went to get my car mapped it would be rude not to show you the results



Somewhat disappointed we couldn't find another 0.2 HP on the day to make a nice round 300 but there you go!
