Hot Start Kit

[PSD]

Does anyone have experience of fitting the hot start kit to Griffith 500 or SE to avoid the delay in restarting if / once over heated, I have been advised that when this is done that the immobiliser should also be replaced, thanks Paul.

The hot start kit just ensures that there is a proper current getting to the starter and has nothing to do with the immobiliser I've never heard of anyone having to change the immobilser or indeed why you'd have to unless it's the immobiliser that's causing a starting issue in which case that's a different issue.

I believe the immobiliser also has a relay that can stick

I think the extra wiring in the starter circuit to and from the imobiliser can add to the voltage drop to the starter solenoid feed, which draws quite a high current. The hot start kit (or you can just use a relay for a few pounds)reduces the power drawn though this circuit, so the wire length no longer matters.

Sounds about right (but i'm sh!te with sparky bits;) ) the kit/relay sorted mine for a while but ultimately i had to get a new uprated immobiliser

Hotstart problem is as much to do with the immobiliser as the wiring... by the time you 'cure' the wiring issue with the kit, the immobiliser has been fried through the overloading that the lack of the (now installed) relay has caused. An effective workaround if the problem continues after fitting the kit is to install a bypass circuit with a hidden switch to just bridge the defective 'cut' if/when the issue arises. Did this as a temporary measure about five years ago and it's still there

Alternatively, a sharp slap on the passenger dashtop will can jolt the immobiliser back to life when it sticks...

I found the solution to my hot start issue was mechanical. The solenoid in the starter got a little sticky over time, so it took more and more current to engage the starter, right up to the point where the wiring and immobiliser couldn't cope any more. Cleaning the solenoid and making the pushrod a little thinner has worked for me for 3 years now.

Still have my click switch hidden away
