Alternator

Gabs · Monday at 9:24 PM

So I been looking at some options on a new alternator for my bus. Currently alternator went pop but don’t ask how. I reckon it’s a 55 amp alternator but seen a 75 and 90 amp upgrades. What I’m reading just need to make sure wiring good on bus so mine was re-wired about 10 yrs back now.
What’s pro and con’s between 75&90 alternator.

Just go for the cheapest, no point having high output unless you have dozens of electrical/electronics in the van, they also wear belts quicker, trust me I know lol

Worth ringing Bristol Auto Electrical to see what they say about re-winding yours, and Sparx whilst your at it

Unless you're running high output spot lights, or a massive sound system with amps and sub woofers, a standard 55A alternator will be more than adequate.
As Justin says the higher the output the more it wears belts and saps the engines power.

Going to order a new one then may recon mine for a backup. All spares help.

Hey Gabs, are you 100% yours is knackered? Could it be something else?

Get yourself a 55amp from power lite. Million times better than the generic Chinese shite the usual suspects all sell.

75 is only required if you’re running lots of additional electrics like gauges, fuel pumps, after market ignition or big stereos etc.
