Chimaera Earthing Points
Discussion
I'm having staring issues (from cold and hot) with my 1999 Chim 500. Sometimes it works fine but the starter sounds quite slow, other times it just clicks and then works on the next attempt, yesterday it clicked three times before it started but then later when hot it started fine (I had already parked facing downhill just in case a jump start was needed!). I've checked the battery voltage and terminals (all ok) so my next course of action is to check the main earth from the battery to the chassis and from the chassis to the engine. Where are these points and how do I access them? Thanks in advance for your help
For a Griffith but virtually the same:

earths are in the following locations:-
- drivers wheel arch in the out rigger cross tube to chassis
- drivers side front chassis leg end by the radiator bottom outlet
- both sides of gearbox tunnel (accessed from inside car) near where dash crosses the tunnel
- rear chassis end behind fuel tank
- rear of engine passenger side onto the head
The main battery to chassis one connects to the transmission tunnel top on the passenger side, bit of a pig to get to.
This may have worked loose but you need to check it anyway as it can give other problems.
Chassis to engine in the drivers side wheel arch worth checking too due to its location.
A temporary jump lead from battery negative to engine will help you see if it's the ground, it's not unusual for it to be on the positive line.

I never knew there was an earthing point chassis to engine on the passenger side. In fact now I think about it my 2000 year car didn’t have one on that side.
Also on my later car there was no earth point on the right hand side of the transmission tunnel. All earths were connected to the left side only and that was common on later cars.

I ran a jump lead from the negative terminal of the battery to the engine - same problem, click on the first try then it staggered into life on the second so it didn't appear to be an earthing issue. I then decided to run a jump lead from the positive terminal of the battery to the solenoid and (having cut away some of the fibreglass on the battery box to gain access) found that the positive wire was very corroded where it went into the battery clamp. I happened to have an unused non-solder type brass clamp left over from my Elan rebuild so I sawed through the cable, pared it back, and clamped the fresh cable into the new battery clamp. The starter now spins over quickly and works every time.
I think I got lucky!
